Bonding Flashcards
What atoms have full outer shells
Noble gasses, meaning they are stable and have an unreactive property
What makes an atom stable
Having a full outer shell
What is an ion
Ion is a charged particle formed when an atom gains or loses electrons. A cation is a positive ion and an anion is a negative ion.
Which side is metals
Left is metals , they lose electrons to make full outer shells.
Which side is non metals
Right side. They gain electrons to gain full outer shells.

Contain 2 or more atoms covalently bonded.
Means that there are 2 atoms covalently bonded in the molecule.
Why is hydrogen diatomic
Because there are 2 atoms in each molecule hydrogen is described as diatomic.
