Question

Which statement describes what is most likely to occur?

Choose 1 answer:
The atoms will move from right to left.
There will be no net movement of atoms.
The atoms will move from left to right.
The atoms will be unable to cross the membrane.

Answer 1

the answer is C

Step-by-step explanation:

As you move from left to right across a period, the number of protons in the nucleus increases. The electrons are thus attracted to the nucleus more strongly, and the atomic radius is smaller (this attraction is much stronger than the relatively weak repulsion between electrons).
