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?

24 answers

b. Sulfur

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.

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

Arsenic,

Hmm I think B

um i still don’t know what the answer is so like someone needs to say the correct answer

the answer is arsenic, it is in the same family and look it up its correct!!!!

yes

arsenic (as)

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

That's random to say on here

c-arsenic

shouldn't it be Nitrogen? it's atomic mass is smaller.
someone help. . .

arsenic

I choose a because it is right my teacher said it was
