Can metal atoms accept electrons and have negative charges? What properties of elements are called metallic properties? How do the metallic properties of elements change in the periodic table?

Metal atoms cannot accept electrons and have negative charges.
Metallicity is the ability of an atom to donate electrons. The higher this ability, the higher the metallic properties.
Metallic properties increase from top to bottom along the group and from right to left along the period.
