1-2 How Elements Bond

Front 1

Ionic bonds

Back 1

loss and gains: Atoms form bonds with other atoms by using electrons in their outermost enrgy level. Four ways to do this; gaining, losing, sharing, or pooling

Front 2

Ionic bons

Back 2

bonds that involve the transfer of electrons through giving and receiving

Front 3

Ions

Back 3

A question of balance: an ion is a charged atom. if an atoms gives an electron its pausitive, if it recieves an electron its negative

Front 4

bond formation

Back 4

ionic bonds are created through the attraction of ions, or opositely charged atoms through the giving and receiving of electrons

Front 5

compounds

Back 5

is a pure substance containing two or more elements that are chemically bonded

Front 6

metalic Bonding-Pooling

Back 6

these are created when metals bond with metals. Valence electrons are loose and can be shared with all atoms in the bond. this pooling of electrons holds atoms together

Front 7

convalent Bonds- Shairing

Back 7

some elements have a tendency to share electrons one family that has this temdency is family 14

Front 8

convalent bonds

Back 8

a bond created when elements share electrons. this creates an attraction of the shared electrons to both nuclei
molecular compounds are convalently bared compounds

Front 9

molecule

Back 9

a neutral particle formed when atoms share electrons- molecules do not consist of ions because electrons are not lost or gained

Front 10

double and Triple bonds

Back 10

when elements share more than 1 electron

Front 11

double bonds

Back 11

when two pairs of electrons are shared

Front 12

Polar and nonpolar molecules

Back 12

atoms can share electrons unevenly

Front 13

polar bond

Back 13

is a bond where electrons are shared unevenly
these polar bonds cause one side of the molecule to be more negative

Front 14

polar water molecule

Back 14

oxygen has a greater share of electrons as an H2O bond. the oxygen end takes a negative charge while the hydrrogen end takes a pausitive. Simular to poles

Front 15

nonpolar molecules

Back 15

do not have this charge, which occurs between bonds of the same element like diatomic elements

Front 16

chemical shorthand

Back 16

alchemists were the first to explore chemistry and they developed symbols for the elements which are no longer used

Front 17

symbols for the atoms

Back 17

tend to be a letter or two letters from an element's Latin naem

Front 18

chemical formulas

Back 18

consist of numbers and chemical symbols to represent what compunds and elements are present

Front 19

oxidation number

Back 19

the number of electrons an atom gains, losses, or shares during a chemical reaction
