Question

A researcher wants to experiment with an element that reacts like phosphorus (P) but has a greater atomic mass. Which element should the researcher select for the experiment?

A. Nitrogen (N)
B. Sulfur (S)
C. Arsenic (As)
D. Silicon (Si)

I choose Arsenic, because it's in the same family as phosphorus. What do you think?

Answer 1

b. Sulfur

Answer 2

I would go with As. N is in the same family, also, but the first element in the series is often less predictive of those that follow so As or Sb would be better choices for P with As being better than Sb. And of course Sb is not one of the answer choices.

Answer 3

I chose Arsenic because it has the greatest mass and also in the same family.

Answer 19

In West Philadelphia born and raised
On the playground is where I spent most of my days
Chilling out, maxing, relaxing all cool
And all shooting some b-ball outside of the school
When a couple of guys, who we're up to no good
Started making trouble in my neighbourhood
I got in one little fight and my mom got scared
And said, you're moving with your aunty and uncle in Bel-Air
