Sagot :
Answer:
Covalent bonds - atoms share the electrons
Ionic bonds - valence electrons of an atom are transferred to another atom
Cation - loses electrons
Anion - gains electrons
Explanation:
Covalent bonds usually occurs between nonmetallic atoms
Ionic bonds occurs when a metal and nonmetal combines to form a compound
The metal loses electrons, becoming a positive ion called a cation.
The nonmetal gains electrons, becoming a negative ion called a anion.
