Question 1

A student is working with four different solid substances: sodium (Na), calcium (Ca), copper (Cu), and iodine (I). Which substance is most likely to break easily into many smaller pieces?

Revolt · Accepted Answer

iodine

Question 2

Looking at the same nonmetal group on the periodic table, how does the reactivity of an element in period 2 compare to the reactivity of an element in period 4?

Revolt · Accepted Answer

The period 2 element would be more reactive because the attractive force of protons is stronger when electrons are attracted to a closer electron shell.

Question 3

Which compound forms a powerful acid and also contains a halogen?

Revolt · Accepted Answer

HBr

Question 4

Which statement best explains why radon and krypton do not bond easily with other elements?

Revolt · Accepted Answer

They have eight electrons in their valence shells, so they are stable without gaining or losing electrons.

Question 5

Where are the most reactive nonmetal elements found on the periodic table?

Revolt · Accepted Answer

at the top of group 17

Question 6

Which element is likely to be the most reactive?

Revolt · Accepted Answer

fluorine (F)

Question 7

What is the most likely reason that nonmetals are electrical insulators?

Revolt · Accepted Answer

Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.

Question 8

When looking across the periodic table from left to right, which of these groups are the first to contain nonmetals?

Revolt · Accepted Answer

group 14

Question 9

Which describes any substance that shatters or breaks easily?

Revolt · Accepted Answer

brittle

Question 10

Which element has a complete valence electron shell?

Revolt · Accepted Answer

argon (Ar)
