UNIT TWO

Question 1

how is a Ionic Bond formed

Answer 1

forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.

Question 2

lone pairs

Answer 2

valence electrons that are left unshared

Question 3

double bond

Answer 3

represents four shared electrons

Question 4

triple bond

Answer 4

represents six shared electrons

Question 5

nonmetal traits

Answer 5

higher elecronegativities that metals, has 5,6,7 or 8 valence electrons

Question 6

metallic bonding

Answer 6

results in the attraction between metals atoms

Question 7

ionic compound

Answer 7

consists of many bonds between positive and negative ions

Question 8

an ionic bond

Answer 8

a transfer of electrons form the less electronegative atom to the more electronegative

Question 9

polar covalent

Answer 9

there is a small difference in electronegativity, atoms share electrons unevenly

Question 10

covalent bond

Answer 10

two atoms share their valence electrons

Question 11

non-polar bond

Answer 11

two atoms are from them same element, their electronegativity is 0

Question 12

electronegativity

Answer 12

a measure of attraction that an atom has for electrons it shared with a molecule

Question 13

ionization energy

Answer 13

energy required to remove an electron from a neutral atom

Question 14

a metal

Answer 14

is an element which is typically hard, shiny, fusible, malleable, and ductile, with good electrical and thermal conductivity.

Question 15

a nonmetal

Answer 15

is an element that does not have the properties of a metal.

Question 16

a metalloid

Answer 16

is an element having intermediate properties of both metals and nonmetals
