Elements and Compounds

Parent Category: Chemistry
Questions about the properties and characteristics of elements as observed in nature and in compounds. Chemical formulas are also converted to and from symbols in covalent or ionic bonds. All the questions you want to ask about the elements and the compounds they form.
Yes, if you add plenty of water. When boiling ham or bacon we oftenput it in water, bring it to the boil, and then discard the first water and replace it for the restof the cooking. This gets rid of some of the salt. However, if youhave a liquid (e.g. a soup or gravy), boiling it will onlyevaporate...
Microbial contamination (such as mold and yeast) can enter after the bottle is opened. Magnesium citrate formulas give microbes an ideal environment to grow.
Oxidation. At high temperature magnesium ignites - and that is  called combustion.
shells : 2 (1st shell), 8 (2nd shell), 8 (3rd shell) electrons...it shares if its outer shell has too many or too little electrons
You can boil water and other liquids out of canned meat but thesalt will stay behind. In fact any solids dissolved in a liquidwill be left behind since when the water boils away, the dissolvedsubstance will precipitate out of solution and will be left behind.Rinsing the canned meat and pouring out...
It is suggested you do this to avoid microbial contamination as it  attracts moisture from the air. Magnesium Citrate does not  decompose quickly. Under the proper conditions it should still be  fine to continue using the oral solution after 24 hours. Consider  refrigeration, tightly sealing the...
1 AMU Neutron is the same electron is almost 0
Yes, Chlorine is a double bond. Chlorine has two 2 valence electrons so that makes it a double bond.

The ionic charges of group 1 and 2 metals are +1 and +2  respectively. Group 15 & 16 the simple mono-atomic ions are -3  and -2. Group 17 ions are -1. This can be explained by the  following elemnts in groups 1 and 2 lose 1 or 2  electrons respectively to achieve a noble gas configuration...
Fluoride is more toxic than lead and just slightly less toxic than  arsenic.
Generally the electrons are transfered from the metal elements to  the nonmetalic elements so that both form stable electron  configurations. For example, in sodium chloride one sodium atom  loses an electron so that it has the stable electron configuration  of Neon and chlorine gains one...
Fluoride is more toxic than lead and just slightly less toxic than  arsenic.
The electrical resistance between subatomic particles is far  reaching from the atomic nucleus and electron cloud. Electrons are  also moving very fast. The probability cloud that determines where  the electrons could be, the orbitals and the nucleus itself, are  still not solid objects. Keep in...

The uses of aluminum are varied and diverse. Today it is used  in commerce, transportation and other industries. Some of its  applications are well known, while others are not so obvious. Apart  from consumer products, the metallic element is also used in glass  creation.      Use in...
soap, its what makes it slippery
If it is heated to 160 degrees Celsius it yo momma melt and  decompose into acetone vapor and calcium carbonate.ngn
In an ionic compound the charges must balance out to zero. Since the nitride ion has a 3- charge and sodium forms a 1+ ion so in sodium nitride there are three sodium ions (Na+) fore every one nitride ion (N3-).
No, it is a non metallic complex ion but it forms salts (Ionic  compounds) just like metallic ions.
Yes because brass is usually made of aluminum and aluminum is high up in the reactivity list.
Utah they get salt from salt mines where the salt lake is    Salt can come from a number of sources. It can be processed from  the sea water with machines, be collected when the water in sea  water has evaporated, or be mined out of silver mines.
Calcium oxide - CaO Ca: 20 electrons Oxygen: 8 electrons Total: 28
An octet electron arrangement is where an atom has 8 valence electrons. It's very stable and unreactive. Some metal atoms tend to donate its electrons and the electrons accepted by non-metal atom. This is called ionic bonding. Some non-metal electron share electron among themselves to achieve...
Sodium chloride (NaCl) is a unique substance, a compound formed by a chemical bond. A mixture involve the existence of min. two different substances.
It depends which form it is in
Radium is a decay product of uranium and is constantly being  produced. U-238 has a half-life of about 4.5 billion years, so  there's still quite a bit left of the original amount on Earth.
The molecules of water are held together by hydrogen bonding between molecules.These are electrostatic bonds (attraction forces between opposite charges) that hydrogen makes with the oxygen of neighbouring molecules. Hydrogen, when bonded to oxygen to form water molecules, is slightly positive and...
Principle of Natural Sciences
They are different chemicals and one is a very strong acid and the  other is a very strong base, respectively.
It is a compound (2 or more elements combined that cannot be  separated) -- water.
Protons and neutrons are called hadrons. A hadron contains three  quarks. Quarks come in 6 flavors (types). These types are up, down,  top, bottom, strange, and charmed. (The names are completely  arbitrary.) A proton contains two up quarks and one down quark  while a neutron contains one up...
If you're asking about whether or not there would be a reaction,  then probably not. You have two compounds with the same anion, so  you will just have a big aqueous solution of chloride ions, plus  some hydrogen and ammonium ions.
dT = (i)(Kf)(m) is the equation that can be used to model the  freezing point depression.   dT represents the change change in temperature.   i represents the amount of ions formed from the dissolution of the  solute.   Kf represents the constant of the freezing point depression of ...
The bubbles you see are most likely Hydrogen gas.
They differ in their structure and properties.  Covalent bonds consist of pairs of electrons shared by two  atoms, and bind the atoms in a fixed orientation. Relatively high  energies are required to break them (50 - 200 kcal/mol). Whether  two atoms can form a covalent bond depends upon...
Yes. But this occurs because salt is soluble in water, in which the  coloring is dissolved. The color is retained by the salt crystals  when they dry.
The sodium chloride crystal arrangement is a cubic crystal lattice (a regular, repeating pattern) or a "salt crystal". Every chlorine ion (negatively charged, as they gain an electron in this case) is surrounded by 6 sodium ions (positively charged, as they lose an electron in this case), as every...
93% sulfuric acid is Virgin sulfuric acid. It is a good drain  opener.
Neither. Silica is a compound of two elements: silicon and oxygen. Oxygen is a nonmetal, silicon is a metalloid.
Ionic compounds intra molecular forces deal with charges which dictates their attractions. Example Na+ and Cl- balance out to form NaCl ( include states in a real equation). While their inter molecular forces, which are the forces between molecules causes them to be set up in a crystal lattice...
No. sulfur does not react with water.
Zinc is a solid, brittle and crystalline at room temperature, but  it becomes ductile and malleable when heated between 110°C and  150°C. It has a melting point of 692.68 K (419.53ºC) and a boiling  point of 1180 K (907ºC) (K=Kelvin)
There can be multiple atoms that have the same number of neutrons,  these are called isotopes. The most common isotope of strontium  (one of four stable isotopes), is strontium 88. This means that the  number of protons and neutrons together in that isotope is 88. And  since all atoms of...
I believe it is 1997
No. A metal plus an acid gives a salt and hydrogen. e.g. sodium +  hydrochloric acid --> sodium chloride (salt) +hydrogen. 2Na +  2HCl --> 2NaCl + H2
Because it's a base, and will react with your dead skin,  effectively exfoliating it.
5869 degrees Kelvin. Rhenium would be the last element to go, with  tungsten right before at 5555 degrees Celsius.
I'm not sure why there would be a biography on an ionic bond but, ionic bonds are when atoms bond by "stealing" an electron from the other.
indicate the total number of p electrons in N(z=7) s electronsin  Si(z=14) 3d electronsin S(z=16)
The products formed are magnesium chloride and water.
electrons and neutrons. When electron # changes it creates an ion.  When neutrons # changes it is called an isotope.
Formula: AlI3 It is ALI3 Not to be confused as AII3
At normal pressure, the alkanes pentane (C5H12) through decane  (C10H22) are liquids. Alkanes are organic compounds consisting of a  single carbon chain of single covalently bonded carbon atoms  surrounded by hydrogen atoms.
I am sorry idk the asnwer it in my book for homework but if u have a bae I can answer any question for that
We know helium, neon, argon, krypton, xenon and radon as the inert or noble gases. You probably don't need examples since there are only six of these elements. Why not just list them all?
You would just call it liquid magnesium, or molten magnesium which  means the same thing.
Molten magnesium is still metallic magnesium. It is in liquid state.
Helium has a full outer shell of electrons, meaning it is stable in its elemental form and does not form chemical bonds or participate in chemical reactions such as combustion.
 NO, it's an trivalent anion ( negative charge species)   
titanium does not exist, therefore, JazzyB wins.
you have to know the conentrations fo at least two of your  compaunds or it is not posible to answere this.
 The two main components of acid rain are sulfur dioxide  (SO2) and nitrogen oxides (NOx).   Sulfur dioxide is a colorless gas released by combusting fossil  fuels that contain sulfur.   Sulfur dioxide reacts with the moisture in the atmosphere to form  sulfur trioxide.   Sulfur...
no, hydrogen can also change your voice because it is also light,  but there are compounds such as sulfur hexafluoride which deepens  your voice.
Because two atomic centres can only create a linear molecule.
Ya, cuz 1 time in Star Trek they had transparent aluminum. For some whales and junk and its totally based on actual events that will take place in the future probably.
This is a physical change, not a chemical one, but you can write an  equation.   CO2(g) --> CO2(l)   However, make sure you write the 2's as subscripts.
A single bond involves one electron from two atoms, bonding them  together with a total of two electrons.
