Question 1

protons

Answer 1

positive charge, 1 amu, in nucleus, determine indentity of atom

Question 2

Electrons

Answer 2

negative charge, 0 amu, outside of nucleus, responsible for reactivity

Question 3

Neutrons

Answer 3

Neutral charge, 1 amu, in nucleus, hold together nucleus

Question 4

Isotopes

Answer 4

Atoms with the same number of protons but different numbers of neutrons

Question 5

opposite charges

Answer 5

attract

Question 6

same charges

Answer 6

repel

Question 7

Coulombic attraction

Answer 7

less # of shells=closer and vice versa
stronger attraction=more protons=stronger attraction
farther down-more electrons shells farther distance=less attraction

Question 8

atomic mass

Answer 8

protons+neutrons

Question 9

atomic number

Answer 9

number of protons

Question 10

isotopes in scientific research

Answer 10

they are used in nuclear medicine, oil and gas exploration, research, and can be used to track small things because of their radioactivity

Question 11

ionic charge

Answer 11

the number of protons minus the number of electrons.

Question 12

Charge

Answer 12

force is directly related to charge
(if charge is 3, force is 3)

Question 13

distance

Answer 13

force is inversly related to distance squared
(3 =1/9, 1/2=4)
