Question 1

the distance from the center of an atom’s nucleus to its outermost electron

Answer 1

atomic radius

Question 2

in general, the radii of atoms decrease in size as you move how?

Answer 2

from left to right across a period of the periodic table

Question 3

__ are smaller than their parent atoms because they have __ electrons than the fixed positive nuclear charge

Answer 3

cations (positive ions)

fewer

Question 4

what type of atom forms cations the easiest?

Answer 4

metals

Question 5

ions that have resulted from a gain of electrons(__) are __ than their neutral atoms

Answer 5

(anions)

larger

Question 6

for a single neutral atom in the gaseous state the minimum energy required to remove the first electron from its outermost shell to make it a cation

Answer 6

first ionization energy

Question 7

which elements have the largest ionization energies and why?

Answer 7

noble gases, they have a full outer energy level and do not gain or give up electrons easily

Question 8

atomic radii generally__from left to right within a period and__top to bottom within a group

Answer 8

decrease

increase

Question 9

the amount of energy required to add an electron to a neutral atom to form a negative ion (anion)

Answer 9

electron affinity

Question 10

what are atoms that have lost or gained electrons?

Answer 10

ions

Question 11

what is the measure of attraction between the nucleus and valence electrons?

Answer 11

electronegativity
