What does it it mean to say that some elements are reactive and form ions easily whereas others do not?
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.
How many particles make up a barium?
its atomic number is 56 its atomic weight is 137 hope that helps
Do atoms often lose or gain electrons?
That depends on the atom. But the basic rule is that the atoms on the left of the periodic table lose valence electrons in reactions, and the ones on the right gain electrons. This is because an atom always wants full outer shells. The atoms on the very right already have full shells, and don't react with anything. These are called noble gases (they're too noble to be with other atoms, get it? :P). The ones on the very left (alkali metals) only have 1 valence electron, so for them it's easier to give away an electron to make their outer shell full. The atoms on the second right (halogens) need 1 electron, so they easily get one in a reaction. NaCl (sodium chloride) is a good example. Here the sodium (Na) atom has one more than it needs, and chlorine (Cl) needs one more. They work perfect together, and together they make the salt that you have in your kitchen :)
Why does argon not form ions?
Atoms become ions by gaining or losing electrons to achieve a noble gas configuration of electrons, which is stable. Argon already has such a configuration and is very stable as it is. Any gain or loss of electrons would make it less stable.
Why is iron not easily reduced?
Reduction is addition of electrons. Iron is [Ar]4s23d6 and can lose electrons (or be oxidized) very easily. Reduction or addition of electrons does not make it stable. The next inert gas is Kr with 36 electrons. It would thus have to gain 10 electrons (be reduced) to get to this structure. This is energetically very unfavorable. All metals as a general rule prefer to lose electrons than gain them.
When metals react with other elements do the atoms of the metals gain or lose?
Metals are likely to make anions. So they lose electrons to get a positive charge. The other elements gain electrons and get negatively charged.
Do anions loose or gain electron?
No, anions do not gain electrons. It is the molecule or atom's ion that gains an electron to make itself a more negative anion.
Is barium an ionic bond?
No. An ion is a positively or negatively charged atom, or group of atoms due to more or less electrons than necassary. Both barium and sulfate are ions, but together they are a compound, not an ion. Barium Sulfate is a chemical compound made up of two ions, a barium ion and a sulfate ion. A Barium ion is Ba+2, meaning it has two less electrons that a barium atom has. The reason for this is because the barium atom has 56 total electrons. Every atom wants to be ion with a filled valence shell, that is to have the same or similar electronic configuration of a noble gas (the elements in the right most column). The valence shell is the outermost shell of electrons and for barium the other shell is 8 electrons. In order for Barium to do this, it has to somehow lose 2 electrons to become similar to Xenon's electronic configuration. Sulfate, SO4 -2, is also an ion. the -2 means it has aqcuired 2 more electrons from another ion. It got those two electrons from the barium atom, simultaneously making the barium atom a barium ion. Sulfate is called a polyatomic ion, meaning an ion made up of more than 1 atom. When the barium ion gives the sulfate ion two electrons, thus making both electronic configurations "happy" they bond together to make an ionic bond, creating the compound barium sulfate.
Do all atoms tend to lose electrons?
No, not all atoms tend to lose electrons. Atoms can gain, lose, or share electrons to achieve a stable electron configuration. The tendency to lose or gain electrons depends on factors such as the number of valence electrons and the element's position on the periodic table.
Can an apple make you lose or gain weight?
gain
How does an ionic bond forms?
Ionic bonds are formed when atoms lose or gain electrons in order to have a full outer shell of electrons to make them stable.One atom pulls an electron from another atom.

How many bonds can Barium make?
Barium can typically form two bonds with other elements. It has two valence electrons that it can share or donate in chemical reactions.

Why do halogens gain electrons?
Halogens have 7 valence electrons, in order to become a noble gas you need 8 so instead of losing electrons, it would be easier just to gain 1. That would make Halogens a negative 1 If you do the dot structure you can see that there is only room to gain 1 electron when forming a bond.
Will doxepin make you gain weight?
yes it will hahaha you lose!!!
Does marijuana make you gain weight since it?
Some will gain weight, and others will lose it. Drugs have different effects on different people, and can either make you feel more hungry (gain weight) or less hungry (lose weight).
