Arrange the following atoms according to decreasing effective nuclear charge experienced by their valence electrons: Cl, Na, P, and S. Rank from largest to smallest. To rank items as equivalent, overlap them. Cl Na P S
Largest Smallest

Cl < S < P < Na

Explanation:

We have to understand the trend for effective nuclear charge before answering the question;

The periodic table tendency for effective nuclear charge: Increase across a period (due to increasing nuclear charge with no accompanying increase in shielding effect). Decrease down a group (although nuclear charge increases down a group, shielding effect more than counters its effect).

Based on this, the elements can be arranged in the following order;

In decreasing order;

Cl < S < P < Na

a is the answer

explanation:

which statement about trans-fatty acids is false?

a. the conversion of cis-fatty acids to trans-fatty acids is inhibited by the presence of antioxidants.

hope this

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
