An ionic bond is formed between a metal and a non metal. The METAL loses an electron (or electrons) and it becomes positively charged.
No. The lower (or 'more negative') the oxidation number, the more electrons the atom has. This is because the oxidation number is a measure of the charge on that molecule and, since electrons have negative charge, more of them give a more negative oxidation number. So if an atom loses electrons during bonding, it has lost some of its negative charge - giving it a more positive oxidation number.
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.
there are 5 bonding electrons. It depends on the number of valence electrons.
Typically, the valence electrons, the electrons in the outermost shell, of an atom are used in bonding.
covalent/ionic bonding.
An ionic bond is formed between a metal and a non metal. The METAL loses an electron (or electrons) and it becomes positively charged.
In covalent bonding atoms share their electrons. In ionic bonding one atom loses electrons while the other gains electrons, so they both become charged and then are attracted together. Valence electrons can also be set aside and not used in the bonding, for example in water oxygen uses two of its six valence electrons in covalent bonding with the two hydrogens, leaving four spare electrons which make up the two 'lone pairs'.
It gains three, loses five, or shares pairs of electrons
Ionic bonds, in which an atom loses or gains an electron, and Covalent bonds, in which atoms share electrons.

Electrons involved in bonding between atoms are valence electrons.
there are 5 bonding electrons. It depends on the number of valence electrons.
Typically, the valence electrons, the electrons in the outermost shell, of an atom are used in bonding.
Covalent bonding involves the sharing of electrons. Ionic bonding involves the transfer of electrons.
All of the valence electrons are used for bonding.
