Science Bonding of Atoms (Chapter 1)

Question 1

Chemical bonding

Answer 1

The combining of atoms to form molecules or ionic compounds.

Question 2

Chemical bond

Answer 2

An interaction that holds atoms or ions together.

Question 3

Valence electrons

Answer 3

An electron that is found in the outermost shell of an atom and that determines the atom’s chemical properties.

Question 4

Ionic bond

Answer 4

A bond that forms when electrons are transferred from one atom to another, which results in a positive ion and a negative ion.

Question 5

Ion

Answer 5

A charged particle that forms when an atom or group of atoms gains or loses one or more electrons.

Question 6

Crystal lattice

Answer 6

The regular pattern in which a crystal is arranged.

Question 7

Covalent bond

Answer 7

A bond formed when atoms share one or more pairs of electrons.

Question 8

Metallic bond

Answer 8

A bond formed by the attraction between positively charged metal ions and the electrons around them.

Question 9

Molecule

Answer 9
