chapter 1-atoms and bounding

Question 1

Atom

Answer 1

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

Question 2

Chemical bonding

Answer 2

the combining of atom of elements to form new substances.

Question 3

Valence electrons

Answer 3

electrons in the outermost shell energy levels.

Question 4

Ionic bonding

Answer 4

bonding that involves the transfer of electrons. (TRANSFERRING)

Question 5

Ion

Answer 5

a charged atom

Question 6

Ionization

Answer 6

the process of reviving electrons and forming ions.

Question 7

Ionization energy

Answer 7

the energy needed for ionization.

Question 8

Electron affinity

Answer 8

the tendency to attract electrons.

Question 9

Crystal lattice

Answer 9

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

Question 10

Covalent bonding

Answer 10

bonding that involves the sharing of electrons. (SHARE)

Question 11

Diatomic element

Answer 11

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

Question 12

Molecule

Answer 12

the combination of atoms formed by a covalent bond.

Question 13

Network solid

Answer 13

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

Question 14

Polyatomic ion

Answer 14

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

Question 15

Metallic bond

Answer 15

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

Question 16

Oxidation number

Answer 16

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