Question 1

isotope

Answer 1

each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei,

Question 2

Which charges attract or repel

Answer 2

opposite charges attract
same charges repel

Question 3

The relationship between coulombic attraction and amount of charge

Answer 3

The size of the charges on the ions makes a difference in the coulombic attraction. The ions with a larger charge will attract more opposite charged ions towards itself compared to ions with a smaller charge.

Question 4

The relationship between coulombic attraction and distance

Answer 4

the greater the nuclear charge (q₁) and the shorter the distance between the nucleus and the outermost electron (r), the stronger the attraction between the nucleus and the electron.

Question 5

Definition of electronegativity

Answer 5

Electronegativity is defined as the tendency of an atom participating in a covalent bond to attract the bonding electrons.

Question 6

atomic mass

Answer 6

protons + neutrons

Question 7

ion charge

Answer 7

protons- electrons

Question 8

of neutrons

Answer 8

mass-protons

Question 9

isotope in scientific research

Answer 9

They emit different levels of raidiation

Question 10

higher electronegativity

Answer 10

highest- flourine
lowest- cesium

Question 11

Pick which atom has a stronger or weaker attraction for valence electrons and explain why

Answer 11

stronger- amount of protons in the nucleus
weaker- distance from the nucleus.
