Back 3

The reason why atoms combine with each other is to gain, lose, or share electrons (achieve full octets)

Back 4

Effective nuclear charge, Ionization energy, and Electron affinity of elements increases from LEFT to RIGHT and from BOTTOM to TOP on the periodic table.

Front 5

Atomic Radii of elements increases from "" to "" and from "" to "" on the periodic table.

Back 5

Atomic Radii of elements increases from RIGHT to LEFT and from TOP to BOTTOM on the periodic table.

Back 6

Electronegativity is the measure of ability of an atom to attract electrons to itself.

Front 7

Electronegativity of elements increases from "" to "" and from "" to "" on the periodic table.

Back 7

Electronegativity of elements increases from LEFT to RIGHT and from BOTTOM to TOP on the periodic table.

Back 8

The type of bond between 2 atoms is determined by their relative electronegativity.

Front 9

Nonpolar covalent bonds have...

Back 9

Nonpolar covalent bonds have small electronegativity difference (0.0-0.4)

Front 10

Polar covalent bonds have ... Differences ranging from "" to ""

Back 10

Polar covalent bonds have Electronegative differences ranging from 0.5 to 1.6.

Front 11

Back 11

Ionic bonds have large electronegative differences which are > 1.7

Front 12

Back 12

Covalent bonds are formed with atoms of similar ELECTRONEGATIVITY in order to achieve full octets.

Front 13

In non-polar covalent bond the electrons...

Back 13

In non-polar covalent bonds the electrons are equally shared.

Front 14

In Polar covalent bonds, electrons are ... This creates... And makes... moments.

Back 14

In Polar covalent bonds, electrons are shared unequally. This creates partial charges which induces permanent dipole moments.

Front 15

Back 15

Ionic bonds are formed between atoms of very different ELECTRONEGATIVITY.

Front 16

Ionic bonds allows atom to achieve full octets...

Back 16

Ionic bonds allows atoms to achieve full octets through the gain or loss of electrons.

Front 17

In lewis structures,... is the central atom.

Back 17

In Lewis structures, usually the least ELECTRONEGATIVE atom is the central atom.

Front 18

Radicals are atoms which contain...

Back 18

Radicals are atoms which contain a single unpaired electron which does not participate in bonding.

Front 19

Formal Charged are created from the...

Back 19

Formal Charges are created from the imbalance between the number of protons within the nucleus and the number of electrons surrounding the nucleus.

Front 20

Back 20

To find out the Formal Charge of an atom compare the number of valence electrons of the atom in the molecule with the original number of valence electrons according to the periodic table.
