4.1 Types Of Chem Bonds

Question 0

Define bond E

Answer 0

E required to break the bond

Question 1

What is a chemical bond?

Answer 1

Forces that hold groups of atoms together and make them fn as a unit.

Question 2

Ionic bonding

Answer 2

A result of the electro static attractions of oppositely charged ions
An atom that easily loses e- reacts with an atom that has a high affinity for e-

Question 3

What type of compound results when a metal reacts with a nonmetal?

Answer 3

Ionic compound

Question 4

Coulomb’s law

Answer 4

E=(2.31 x 10^-19 J nm)[(Q1 Q2)/r]
Where Q1 and Q2 are the numerical ion charges
r is the distance between the ion centers in nm

Question 5

Angstroms =

Answer 5

10^-2 nm

Question 6

1nm =

Answer 6

10 angstroms

Question 7

When Coulomb’s law gives a negative answer

Answer 7

There is an attractive force: the ion pair has a lower E than the ions separately

Question 8

If Coulomb’s law gives a positive E

Answer 8

That indicates a repulsive force

Question 9

Define bond length

Answer 9

The distance between the atoms where the E in minimal

Question 10

Covalent bond

Answer 10

e- shared by nuclei

Question 11

What type of bond is formed when the atoms are not so different that they completely transfer e- but are different enough that unequal sharing results?

Answer 11

Polar covalent bond
