Which periodic group has the smallest atomic radius?

Alkali metals

Halogens

Noble Gases

Transition metals

Electronegativity is...

how good an atom is at attracting electrons

the ability of an atom to lose electrons

the energy required to remove an electron from a specific atom

how easy it is to make friends.

As you move down a Group on the periodic table, what happens to the size of the atoms?

they stay the same

they get larger

they get smaller

Put these in increasing order:
F, N, B

B < N < F

B < F < N

N < F < B

F < N < B

Put these in increasing order:
C, H, and O

H < C < O

H < O < C

O < C < H

C < H < O

Which has the greater EN:
Cl or Al?

Choose the set that goes from lowest to highest electronegativity?

Cu, Mg, Sr, Ca

F, Cl, Br, Si

Cs, Rb, Ca, Mg

Zn, Cd, Ag, Cu

Which of the following is the least electronegative element?

oxygen

potassium

fluorine

nitrogen

Put these in order of increasing electronegativity:
Se, S, and O

Se < S < O

Se < O < S

O < S < Se

S < Se < O

10.

Which is smaller... Mg or Mg²⁺ ?

Mg because it gains an energy level

Mg due to extra electron repulsion

Mg²⁺ because of extra electron repulsion

Mg²⁺ because it loses an energy level

11.

What makes a valence electron more attracted to the nucleus?

less distance between the nucleus and having less protons

less distance between the nucleus and having more protons

more distance between the nucleus and having less protons

more distance between the nucleus and having more protons

12.

Going down the group, the atomic radius of elements increases. Why is that so?

The number of shell (n) increases

Shielding effect increases

Nucleus attraction towards valence electrons weaker

All of the above

13.

As you move down the periodic table atoms get bigger. This is because ____________.

The atoms have more mass.

The atoms have more protons.

The atoms have more energy levels

The atoms have more nuetrons

14.

Which atom has the largest atomic radius?

potassium

rubidium

francium

cesium

15.

List these 3 elements in order of increasing atomic radius:

Be, F, C

Be, C, F

F, C, Be

16.

How does the number of protons in the nucleus affect the attraction between the nucleus and valence electrons?

The fewer protons there are, the stronger the attraction is

The more protons there are, the stronger the attraction is

The number of protons will not affect the attraction between the nucleus and valence electrons

17.

Order the following in increasing atomic radii:
Ra, Be, Ca, Rb, H

Ra, Be, Rb, H, Ca

Rb, H, Ca, Be, Ra

Ra, Rb, Ca, Be, H

H, Be, Ca, Rb, Ra

18.

If a potassium atom lost one electron, what would be the symbol for that ion?

19.

Which of the following is in the correct order of size?

Anion > Atom > Cation

Atom > Cation > Anion

Cation > Atom > Anion

Anion > Cation > Atom

20.

Coulombic attraction affects the atomic radius, especially when moving across the periodic table. Which of the following answers explains why this happens?

There are more protons, so the attraction between opposite charges is stronger.

There are more electrons, so the attraction between opposite charges is stronger.

There are more neutrons, so the attraction between opposite charges is stronger.

Coulombic attraction does not depend on subatomic particles.
