Bonds

Question 1

chemical bonds

Answer 1

two atoms help together

Question 2

ionic bond

Answer 2

brittle/hard to move: a total by opposite charge: usually a metal and a nonmetal

Question 3

covalent

Answer 3

held together by sharing electrons: two nonmetals: not always equal sharing (polar molecule)

Question 4

metallic bond

Answer 4

easy to bend and move: makes electricity easy: two metals: held together by everyone sharing electrons (sea of electrons)

Question 5

highest melting point to lowest

Answer 5

metallic, ionic, covalent

Question 6

highest boiling point

Answer 6

covalent

Question 7

valence electrons

Answer 7

the outermost ring of electrons: each column has the same (1A, 2A…)

Question 8

oxidation number

Answer 8

charge of the atom when the atom is stable metals

Question 9

metals vs nonmetals

Answer 9

divided by the stair step lines materials to the below and nonmetals to the right: if it touches its a metalloid

Question 10

atomic mass

Answer 10

as you go down and to the right they get heavier

Question 11

atomic radius

Answer 11

(size of atom) as you go down you add more rings more size: as you go to the right they get smaller (more compact)

Question 12

electronegativity

Answer 12

same trend: when bonded how selfish is the atom w/ the electron

Question 13

ionization energy

Answer 13

same trend: how much energy you need to give up an electron

Question 14

electron affinity

Answer 14

same trend: how much energy is released when the atom gains an electron

Question 15

trend for electron, ionization, electronegativity

Answer 15

right and up: fluorine has the most
