Question

Electronegativity tends to increase from left to right across a row, because
A. the number of energy levels increases.
B. the valence electrons are located farther away from the nucleus.
C. the attraction between the nucleus and the valence electrons increases.
D. the shielding effect increases

Answer 1

Answer 2

think about each option one at a time, and see if it is true, or could be true. that will help to eliminate one or two right away

Answer 3

It would automatically eliminate B, right?

Answer 4

you can.

Answer 5

if you look carefully, you'll see that A and B are actually the same answer, arent they?

Answer 6

That's what I was kinda thinking, but didn't know if I was crazy or not.. would the correct answer be D?

Answer 7

shielding increases when the levels in between the nucleus and the valence level increases. In this case, you're not adding levels, you're filling an incomplete level.

In this case, A, B, and D are all based on adding levels (which this problem isn't doing, since it's going across a period, not down a group)

Answer 8

Oh okay, I see that now. Sorry. Lol But thank you for helping me with all of these, you're the best.

Answer 9

Answer 10

I have about 7 more questions to complete my study guide for my test, could you help me if you know them?

Answer 11

sure. it would also help if you told me what you think, that way you'll be sure to remember them better

Answer 12

Okay, I can do that, some of them I have already answered and really just need another opinion, but on others, I could really use your help.

Answer 13

sure. just remember to ask a new question every time, or i can't get more than 1 medal ;-)
