Quite often yes with metals. Not always though. With carbon it forms covalent bonds.
ionic and covalent
No. Sodium can only form ionic bonds.
Ionic bonds are chemical bonds by positive ionic charge(normally hydrogen , metals +) and negative ionic charge(chlorine ,sulphur etc ) that bind to form compounds.
Only sodium and chlorine will form ionic bond. the other pair given here will form covalent bond
No. Beryllium has only two valence electrons and forms ionic bonds with chlorine, not covalent bonds. Beryllium atoms form 2+ ions, and chlorine atoms form 1- ions in order to form the ionic compound beryllium chloride, BeCl2.

Ionic bonds are chemical bonds by positive ionic charge(normally hydrogen , metals +) and negative ionic charge(chlorine ,sulphur etc ) that bind to form compounds.
A chlorine atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons.
Sodium chloride has ionic bonds.
Chloride is an ion that can form ionic bonds. Elemental chlorine is covalently bonded.
No, Oxygen forms covalent bonds
No. Sodium can only form ionic bonds.
Chlorine usually forms ionic bonds with metals and covalent bonds with nonmetals,but it also forms coordinate bonds in some cases ,in HCl chlorine may form hydrogen bonding.
Ionic bonds are chemical bonds by positive ionic charge(normally hydrogen , metals +) and negative ionic charge(chlorine ,sulphur etc ) that bind to form compounds.
They do not have any bonds in common. Calcium and chlorine atoms form an ionic bond and hydrogen and nitrogen form a polar covalent bond.
Covalent bonds are between non-metals only. Ions in covalent bonds share electrons. Ionic bonds are between a non-metal and a metal and the ions transfer electrons. Sodium (Na) is a metal and chlorine (Cl) is a non-metal. Therefore, sodium and chlorine form an ionic bond, in which ions transfer electrons.
Only sodium and chlorine will form ionic bond. the other pair given here will form covalent bond
