Why does sodium give yellow color in the flame test?
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.
What happens to atoms of most nonmetals when they react with other elements?
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.
How many sodium atoms are present in 0.2310 g of sodium?
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.
Explain how does the sea of electrons model of metallic bonding explain the shared characteristics of metals?
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.
Why does sodium and chlorine atoms form a ionic bond?
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.
When metals react with other elements what happens to the valence electrons of the the atoms?

What at the atomic level what makes elements reactive?
their atoms take,give,or share electrons with other atoms :)

Does sodium chloride give or take electrons?
No
Why sodium ions are more stable than sodium ions why?
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.
Why does sodium give yellow color in the flame test?
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.

Do metals take electrons or give electrons to the atoms they bond with?
Metals give up electrons while non-metals gain electrons
