Flashcards in Section 1 science Deck (17):
1

Chemical bonding

The combining of atoms to form molecules or ionic compounds

2

chemical bond

an interaction that holds atoms or ions together

3

valence electrons

an electon that is found in the outermost shell of an atom and that determines the atoms chemical properties.

4

ionic bond

a bond that forms when electrons are transfered from one atom to another, which results in a posotive ion and a negative ion

5

ion

a charged particle that forms when an atom or group of atoms gains or loses one or more electron

6

crystal lattice

the regular pattern in which a crystal is arranged

7

covelant bond

a bond formed when atoms share one or more paris of electrons

8

molecules

the smallest unit of a substance that keeps all of the physical and chemical properties of that substance

9

mettalic bond

a bond formed by attraction between posotivley charged metal ions and the electrons around them

10
