2.
W hich of the following is a true statement?
a. Elements in the same period have similar properties because they have the same number of e’s in outer level.
b. Elements in the same group have similar properties because they have the same number of e’s in outer level.
c. Elements in the same period have similar properties because they have similar isotopes of p’s and n’s.
d. Elements in the same group have similar properties because they have similar isotopes of p’s and n’s.

4.
W hich of the following comparisons is false about sizes of atoms?
a. K is bigger than Na b. Cl is bigger than Br c. Al is bigger than B
d. P is bigger than N
The further down in a group a metal element is,
a. the more reactive it is because the outer electrons are further away and easier to lose.
b. the less reactive it is because the outer electrons are further away and harder to lose.
c. there is no difference in reactivity, because there is the same number of electrons in outer level to lose or gain.
d. the more reactive it is because radioisotope stability decreases with larger atoms.
5.
The most reactive nonmetal element would be:
a. radon, because it is in the lower right corner of the table, meaning its electrons are furthest from the nucleus.
b. hydrogen, because it only has to gain one electron.
c. fluorine, because it is a small atom and only has to gain one electron in the second energy level (near nucleus).
d. oxygen, because there is so much of it available in the air and it is a large atom and easy to gain electrons.
6.
Based on their location on the periodic table, which of the following statements is false?
a. oxygen is more reactive than sulfur b. calcium is more reactive than beryllium
c. potassium is more reactive than lithium d. iodine is more reactive than chlorine
7.
W hich of the following lists contains only alkali metals?
a. Be, Mg, Ca, Sr b. Cr, Mn, Fe, Co c. Li, Na, K, Rb
8.
9.
W hich of the following lists contains only metalloids?
a. Al, Si, Ge, As b. Cr, Mn, Fe, Co c. B, Ge, As, Te
d. F, Cl, Br, I
d. Zn, Cd, Hg, W
W hich of the following statements is true?
a. All halogen atoms have 8 electrons in their outer level.
b. All members of the oxygen group of ions will have a charge of 2-.
c. All group 15 elements will react by losing 5 electrons.
d. Hydrogen is classified as a nonmetal because it always reacts by gaining an electron.
10. An atom is known to have 5 energy levels, and have 3 electrons in its outer level. W hich of the following
statements is false about this atom?
a. Its ion would have a 3- charge. b. It is an atom of indium. c. It has 49 p and 49 e. d. It is not stable.
