 Polyatomic compounds combine polyatomic ions with metals  Poly atomic ions are groups of atoms that tend to stay together and carry an overall ionic.

Whenever a bond is formed (of whatever kind), energy is released; that makes the things involved more stable than they were before. The more bonds an atom.

Covalent Bonding Occurs when atoms share electrons Different from ionic bonding Ionic Bond = Atoms completely transfer electrons Covalent bonding occurs.

For each of the following say if it is ionic, covalent.

Bonding  Compounds are formed when atoms join together.  They are held together by bonds.  Non – metal elements are joined together by a Covalent Bond.

COVALENT BONDING. HOW DOES IT WORK? Covalent bonding takes place between nonmetals atoms only Atoms try to attain noble gas structure by sharing electrons.

MOLECULAR COMPOUNDS. Bonding Atoms combine with each other in two general ways: 1. Ionic Compounds: transfer of electrons from one atom to another June.

Covalent Bonding This occurs when non metal atoms bond together. They share pairs of electrons to give oneanother complete outer shells. Here covalent.
