An atom of sodium has one valence electron. When a sodium atom loses this electron to another atom, it becomes a sodium ion.
Sodium gives a yellow color in the flame test because when it is heated, the electrons in the sodium atoms are excited to higher energy levels. When these electrons fall back to their original energy levels, they release energy in the form of light, and for sodium atoms, this energy corresponds to a yellow color.
They tend to gain electrons when reacting with a metal. Metals generally are short of a full octet by 1 to 4 valence electrons. It is easier to drop 2 electrons than try to gain 6 electrons. The elements in group four can go either way, but the other metals will give up electrons, and non-metals will take them.
To find the number of sodium atoms in 0.2310 g of sodium, you need to convert the mass to moles using the molar mass of sodium (22.99 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. This calculation will give you the number of sodium atoms present in 0.2310 g of sodium.
Basically, electricity is a force caused by electrons hitting each other. The electron sea model explains the conductivity of transition metals by showing that they hang onto their many electrons loosely and are practically floating in them. With so many free electrons, it's a lot easier to conduct electricity.
All atoms want to have a perfect outer layer of 8 electrons. Sodium's electron configuration is 2-8-1, where each number represents a layer of electrons, with the last number being the outer layer. Chlorine has an electron configuration of 2-8-7. If sodium were to lose and electron and give it to chlorine, both of these atoms would then have the perfect outer layer of 8. That's what happens when the two form an ionic bond.

their atoms take,give,or share electrons with other atoms :)

No
If you're asking why Sodium ions are more stable than Sodium atoms, it is because most all atoms, besides Hydrogen and Helium, are more stable when they have 8 electrons in their valence shell. They all "want" to be like those atoms which have 8 electrons in their valence shell (the noble gasses). A Sodium atom has 11 electrons, and it is very easy for it to "give up" one electron to something else so that it will be like Neon, the closest noble gas.

Metals give up electrons while non-metals gain electrons
