Bonding Elements Crossword

Type
Crossword
Description

Atoms that gain electrons and become negative. Anion
Atoms that lose electrons and become positive. Cation
This is the type of bond where electrons are shared between atoms. Covalent Bond
Type of bond where atoms give electrons to other atoms and there's an attraction between oppositely charged ions. Ionic Bond
Atoms with either a positive or negative electrical charge. Ions
These touch the staircase in the periodic table and have properties of both metals and non-metals Metalliods
These are found to the left of the staircase and form ionic bonds with non-metals. They give away electrons and become a positively charged except for hydrogen. Metals
These are found to the right of the staircase and form covalent bonds with each other, or take away electrons from metals to form ionic bonds and become negatively charged. Non-Metals
Atoms want to have eight electrons on their outer shell to become stable. Octet Rule
The total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom. Oxidation Number
The electrons found on the most outermost shell of an atom. This is where chemical reactions and bonding take place. Valence Electrons
The outer most shell of an atom. Valence Shell
