Parent Category: Elements and Compounds
Questions about the structure of atoms/molecules and the resulting properties such as shape, polarity, and number of subatomic particles.
shells : 2 (1st shell), 8 (2nd shell), 8 (3rd shell) electrons...it shares if its outer shell has too many or too little electrons
1 AMU Neutron is the same electron is almost 0
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...
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...
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...
electrons and neutrons. When electron # changes it creates an ion.  When neutrons # changes it is called an isotope.
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
A single bond involves one electron from two atoms, bonding them  together with a total of two electrons.
No. A compound is a mixture of different elements. They can be in  different proportions. Examples are CH3 and CH4.
They go where they are not. They are not on the other side of the  membrane. So they go there. In fancy words, it is called going down  the concentration gradient. It is diffusion.
1.4 x 6.02x10^23 = 8.428x10^23 molecules
Electrons are a type of fundamental particle known as a Lepton.  Protons how ever are made up of quarks. A proton has a quark  structure of up, up, down (UUD). The up quark has a charge of +2/3  and the down has -1/3 which gives the proton its overall positive  charge. The up and down quark both...
The inner most shell can have up to 2 electrons, the next can have  8 electrons, the third shell from the center can have 18 electrons.
You mean, what happens when positive and negative charges are equal? That is simple, the equal opposite cancel each other out and we have an electrical neutrality
im learning this in science, the most direct answer is 8, the equation to figure this out is 2 times n times n where n is the energy level in this case, 2, so 2 times 2 times 2=8. but once you get to the 18th element (i believe it is potassium) and above this equation no longer applies, but the most...
That's called an element. The 90 or so naturally occurring  elements, in various combinations, make up all matter in the  universe.
The maximum number of electrons in any p orbital is 6.
0 atoms. I'm guessing you are suggesting table salt, which is  sodium chloride. Sodium chloride only contains sodium and chlorine  and no oxygen.
ions, with a loss of electrons it would be called a cation and with  a gain it would be called an anion
yes we have various isotopes on the difference in the number of  neutrons
A cation is a positive ion. To get 2 positive charges the atom  would need to lose 2 electrons. As its configuration is 2,8,2, this  is what it is likely to do when it reacts as the resulting ion has  an inert gas structure.
It is the neutron that has about the same mass as a proton. Recall that the tiny electron has a mass much less than one thousandth that of a proton.
kerosene is unsaturated hydrocarbon
An ionic bond, most definitely, Cupric sulfide or copper sulfide;  the ratio of the ions and their oxidation state vary. A more common  compound might be copper sulfate Cu2(SO4), which is the copper salt  of sulphuric acid and it can be formed by reacting metallic copper  with sulphuric acid.
Actually, the nucleus is incredibly small and the neutrons are contained there.
Why are atomic weights given as fraction and not whole numbes like  weight = proton + neutrons? Because they are taking an average of  the weight of the naturally occurring isotopes, so that when you  use the tables and you are using atoms from earth (most do :D )  then these fraction values...
The mass of one specific isotope, called the mass number, is the  total number of protons plus neutrons. M = P + N   Therefore, for atomic number P, you would take the mass  number minus the neutrons: P = M - N.
The atomic weight of Aluminium is 26.9815 amu i.e. 4.5x10^-23 grams.
  == Well if you mean sunflower seeds you cant use youre teeth without even braking im very used to it myself i havent broken a sedd in months ==   === If you are talking about a different seed i dont know wich one youre talking a bout you need to bve more specific ===
Probably. He just got a new daughter, and therefore he's taking a break. Maybe he will have a comeback with HBK? :)
To calculate the relative atomic mass of an element (which is by  its definition an average), you need the mass number and relative  abundance of each isotope present.   Suppose we have the following data from the mass spectrometer:   first isotope mn X, abundance A%   second isotope mn Y...
Bromine is a none metal element. atomic number of it is 35.
2 or more electrons, because Oxygen already has 8.
no. elements are categorized by the number of protons. also ifthere are no protons. then it is no longer an atom
Since protons and electrons carry the same but opposite charges, the charge of a single proton is often given in units as +1. More specifically, a proton's electrical charge is e divided by the square root of two, .707 x 0.16E-18 Coulomb. This is the effective (RMS) charge, or 0.113137E-18 Coulomb.
An ion is formed.   A positive ion if there are fewer electrons than protons.   A negative ion if there are more electrons than protons.
The electron configuration of an atom determines how it behaves  when it comes into contact with another atom.
Light causing electrons to be released from the surface of a metal.
There will be no double bonds between carbon atoms in a saturated fatty acid.
The element carbon has the ability to link with itself in long chains containing from two up to hundreds of units. It can also form rings and bond with many other elements and they often with each other. This ability means that many millions of possible compounds can be formulated. The chemistry of...
Atomic number 10 is Nickel but it's atomic number is 28 not 22. Titanium has an atomic number of 22.
The number of protons in an atom is its atomic number.
Ozone, O3 gaseous elemental molecule
Mass number. this is at least equal to the atomic number as in hydrogen-one. In all other elements there are neutrons in all of their isotopes.
Type your answer here... give me answers
radioactive elements, tracers, are used in molecular research to investigate the movement of atoms and molecules through a biological system. At various intervals the movement of the radioactive atoms can be traced using photographic film.
A proton has a charge of +1 and an electron has a charge of -1.
Protons,Neutrons, and Electrons. Which are all inside the nucleusof the atom.
not been discovered yet
elecron can move from atom to atom...yes
electronic configuration is important for the matter to be stable or octet to be complete
The nucleus which includes the protons and neutrons, and the  electron cloud which contains the electrons. If you want to get  into true quantum mechanics, then there are the quarks, the  leptons, the bosons, gluons, etc.
it tells the weight of ine atom in the element
This process of decaying is called a beta decay. The produced proton remains in the nucleus and the electron is released from the atom.
yes protons have a positive charge and neutrons have neutral charges. the electrons have a negative charge. im a kid and i knew that. hahaha. its okay though im in highschool and im learnin this stuff you probably frogot.
TWO types of subatomic particles?? Gosh, the basics are the electrons, neutrons, and protons. Then you add muons, gluons, 6 quarks and so on, and you come up with many particles. And that's just for matter.If you consider anti-matter, you have positrons, anti-protons, anti neutrons, etc etc etc.
The atomic mass unit (amu), or Dalton (Da) or, sometimes, universal  mass unit, is a unit of mass used to express atomic and molecular  masses. It is the approximate mass of a hydrogen atom, a proton, or  a neutron.   . 1 u = 1/NA gram = 1/ (1000 NA) kg (where NA is Avogadro's number)  1 u =...
Caesium and Xenon, with 36 isotopes each
Tin is the element with the most stable isotopes, ten. Xenon is second with nine isotopes. Both Xenon and Cesium have 36 possible isotopes, but 27 of Xenon's and 35 of Cesium's isotopes are radioactive. This means that they decay over time and "shed" particles. Hydrogen has the smallest amount of...
Tritium, a radioactive isotope of hydrogen.
all you need to know is how many protons and neutrons are in the atom.
Neutrons have no charge for the same reason that plastics (and other insulators don't). They just don't. This isn't a great answer, but the thing with charge is that we don't really know what "charge" is. We know that certain "charged" objects will attract some objects, while repelling . We also...
Iron is a metal element. Atomic number of it is 26.
It isn't possible to completely make a Lewis structure in this format, but here's the idea:CH3COO- is acetic acid, the acid in vinegar. The two carbons are bonded, with one carbon having 3 hydrogens around it. The other carbon has a double bond with one oxygen, and a single bond with the other...
Carbon is element number 6 on the periodic table; therefore, it has 6 protons and 6 electrons.
Boron. It's atomic number is 5, so it contains 5 protons.
Fluorine has 7 valence electronsFlourine has 9 electrons. So the electronic configuration would be (2,7) the valence shell would have 7 valence electrons
yes, oxygen has 8 electrons and uranium has 92 electrons
