2.2 Chemical Bonds

Question 1

are interactions that stabilize the outer energy levels of atoms.

Answer 1

chemical bonds

Question 2

If the outer shell is not full, the atom will form chemical bonds with other atoms until it satisfies its outermost shell requirements. The atom is said to be

Answer 2

reactive

Question 3

If the outer shell is full, the atom will not react with other atoms and is said to be

Answer 3

inert

Question 4

two biologically important types of chemical bonds

Answer 4

ionic bonds and covalent bonds

Question 5

chemical bonds created by the TRANSFER of electrons from one atom to another atom.

Answer 5

Ionic bond

Question 6

The transfer of electrons in an ionic bond creates two ionized atoms

Answer 6

one a cation and the other an anion

Question 7

chemical bonds that form between neutral atoms rather than ionized atoms

Answer 7

covalent bond

Question 8

Ionic bonds are common in the formation of inorganic compounds such as

Answer 8

acids, bases and salt

Question 9

differentiated covalent and ionic bond

Answer 9

ionic bond is TRANSFER while covalent is SHARING

Question 10

exists when one pair of electrons are shared between two atoms

Answer 10

single covalent bond

Question 11

exist when two pair of electrons are shared between two atoms

Answer 11

double covalent bond

Question 12

are created by UNEQUAL sharing of the electrons due to the electronegativity of the atoms

Answer 12

Polar covalent bond

Question 13

are those where the atoms share the electrons EQUALLY

Answer 13

non polar covalent bond

Question 14

-chemical substances consisting of atoms of ONE OR MORE SAME ELEMENTS held together by covalent bonds

Answer 14

molecules

Question 15

chemical substances made up of atoms from TWO OR MORE DIFFERENT ELEMENTS, regardless of the type of bonds joining them together.

Answer 15

compounds
