Bromine has 7 valence electrons available for bonding.
Nitrogen has 5 electrons available for covalent bonding. It has 5 electrons in its outer shell, meaning it can form stable covalent bonds by sharing these electrons with other atoms.
Phosphorous has a total of 15 electrons, and of those, 3 of them are valence shell, or bonding electrons. So, 12 electrons are core electrons, and are non-bonding.
Nitrogen has three non-bonding electrons.

A sulfate ion consists of one sulfur atom, four oxygen atoms, and two "excess" electrons from another source. Each sulfur atom has 16 electrons, each oxygen atom has 8 electrons, so that the total is 16 + (4 X 8) + 2 = 50. The question of "bonding electrons" is not quite so clear. When acting as an ion, each sulfate ions has two electrons available for ionic bonding. Internal bonding within each sulfate ion is generally supposed to correspond to two sulfur-oxygen double bonds with four bonding electrons each, two sulfur-oxygen single bonds with two bonding electrons each, and the two excess electrons, for a total of 14.
Bromine has 7 valence electrons available for bonding.
Two valence electrons
Lithium have available for bonding one electron.
Argon is a noble gas and being as its highest energy level is completely filled there are no electrons available for bonding in argon.

Nitrogen has 5 electrons available for covalent bonding. It has 5 electrons in its outer shell, meaning it can form stable covalent bonds by sharing these electrons with other atoms.
Aluminum (Al) has three valence electrons available for bonding. It is located in group 13 of the periodic table, where elements typically have three electrons in their outermost shell. These valence electrons can participate in chemical bonding, allowing aluminum to form various compounds.
Each potassium atom has one valence electron available for bonding.
Phosphorous has a total of 15 electrons, and of those, 3 of them are valence shell, or bonding electrons. So, 12 electrons are core electrons, and are non-bonding.
Nitrogen has three non-bonding electrons.
