What distinguishes one <b>element</b> from another?

The number of protons in an element’s nucleus, which is known as the element’s atomic number.

Describe the formation of an <b>ionic compound</b>

Ionic compound forms through the electrical force between oppositely charged ions. These compound are between a metal and non-metal only.

What is the different between an <b>ionic bond</b> and a <b>covalent bond</b>?

Ionic bond result when electrons are transferred between atoms. Covalent bonds result when valence electrons are shared between atoms.

How does a <b>molecule</b> differ from an <b>atom</b>?

A molecule is two or more atoms held together by covalent bonds. An atom is the smallest part of an element.

Explain why a hydrogen atom can become either an <b>ion</b> or a part of a molecule.

It can become an ion because it can lose or gain an electron. It can become a part of a molecule because it can form covalent bonds with other atoms to gain a full valence shell.

A sodium atom has one outer electron, and a carbon atom has four outer electrons. How might this difference be related to the types of compounds formed by atoms of these two elements?

The number of electrons in an atom’s outer shell directly relates to what other atom’s it can bond to. For atoms to bond they usually bond to another atom(s) that will cause they’re outer electron shell to become complete creating a stable compound.
