1
Q

Atom

A

smallest part of any element that retains all the properties of that element.

2
Q

Chemical bonding

A

the combining of atom of elements to form new substances.

3
Q

Valence electrons

A

electrons in the outermost shell energy levels.

4
Q

Ionic bonding

A

bonding that involves the transfer of electrons. (TRANSFERRING)

5
Q

Ion

A

a charged atom

6
Q

Ionization

A

the process of reviving electrons and forming ions.

7
Q

Ionization energy

A

the energy needed for ionization.

8
Q

Electron affinity

A

the tendency to attract electrons.

9
Q

Crystal lattice

A

the placement of ions in an ionic compound results in a regular, repeating, arrangement.

10
Q

Covalent bonding

A

bonding that involves the sharing of electrons. (SHARE)

11
Q

Diatomic element

A

an element whose atoms can form covalent bonds with another atom of the same element.

12
Q

Molecule

A

the combination of atoms formed by a covalent bond.

13
Q

Network solid

A

covently bonded substances that have high melting point because its molecules are bigger.

14
Q

Polyatomic ion

A

a group of covalently bonded atoms that acts like a single atom when combining with other atoms.

15
Q

Metallic bond

A

bonds formed by metal in which the outer electrons of the atom form. (SEA)

16
Q

Oxidation number

A

the number of electrons an atom gains or looses, or shares when it forms chemical bonds.
