By gaining 3 electrons
To achieve octet configuration (stable)
Ammonia is a molecular compound. The hydrogen atoms share electrons with the nitrogen atom.
Li3N because Lithium will give 3 electrons to complete Nitrogen's octet as N has 5 electrons in it's valence shell and needs 3 more to complete it's octet.
They achieve stable configuration by sharing their electrons in their outermost shell.
2-. Sulfur is in group 16, it has 6 valence electrons and requires 2 more electrons to achieve the stable octet,
Magnesium is group II and has two valance electrons to donate to achieve the octet state. Nitrogen has 5 valance electrons so it accepts 3 into its outer shell to make an octet. So Mg3N2
Nitrogen always has 7 protons, otherwise it is not Nitrogen. Nitrogen 20 means that there are 20 protons. Unless it has an ionic bond, then there are also 7 electrons. If it is an ion, then there are 10 electrons.
To achieve octet configuration (stable)
There are 16 electrons in this ion. 7 from nitrogen, 8 from oxygen and the other one is from the ionic charge.
nitrogen can form an ionic bond
In chemistry, a "salt" is an ionic compound. An ionic compound is formed when there is a transfer of electrons from one element to another. Common example of ionic compounds are baking soda (NaHCO3) and table salt (NaCl). Nitrogen dioxide cannot be referred to as a salt because it is not an ionic compound. Rather, it is a covalent compound. This means that the bonds within the compound are formed by the sharing of electrons and NOT the transfer of electrons. Instead of salt, nitrogen dioxide can be referred to as a molecule.
covalent bond because two electrons are shared
Ammonia is a molecular compound. The hydrogen atoms share electrons with the nitrogen atom.
Covalent. The Nitrogen atom shares 3 of its outer electrons with 3 hydrogen atoms.
Li3N because Lithium will give 3 electrons to complete Nitrogen's octet as N has 5 electrons in it's valence shell and needs 3 more to complete it's octet.
They achieve stable configuration by sharing their electrons in their outermost shell.
The compounds in the system nitrogen-sulfur are not ionic.
