last option: Ar

Justification:

The metallic character of the elements in the periodic table increase from right to left and from top to bottom.

That means that the elements of groups (rows) 1 and 2 and periods (columns) 6 and 7 are the most metallics, and the elements of groups 17 and 18 and periods 1 and 2 are the least metallics.

Na, Mg, Al, P and Ar are in the same period (row) so you can differentiate their metallic character by the rule that the more to the right on the row the less metallic the element is.

Na (left end the row) is the most metallic and Ar (right end of the row) is the least metallic.

P and Ar are less metallic.

Then, the list arranged in order of decreasing metallic character is:

Na > Mg > Al > P > Ar.

Therefore, the answser is Ar.

Answer from: Quest

when—without warning—something provokes your anger, you may struggle not to succumb to it. since what typically makes you mad is feeling powerless in the face of what seems unfair, your anger is mostly an attempt at a “quick fix” to right the balance. it’s as though you’re raising a fist in protest, proclaiming that you’re not going to capitulate to such injustice.

there are, however, a multitude of problems related to this immediate, push-back reaction of anger. and probably the key one is that almost never does it resolve the issue that gave rise to it. such reactive anger is probably best understood as self-defeating. as david burns, the author of the seminal self- book feeling good, observes: if realistically, acting on your anger is to make any sense, it needs to meet two criteria—which, in almost every case, is frankly impossible. that is, your anger must:

be directed toward a person who has intentionally (and needlessly) behaved in a hurtful way toward you; and

be beneficial or advantageous to you (i.e., assist you in achieving a desired goal).

i think you’ll agree that only rarely can you claim that your anger is both warranted and , whether to yourself or the relationship.

so let me offer you a two-step alternative to abandoning your better judgment and giving in to the temptation of anger—one that should neutralize your anger in seconds. or, when you’re really angry, in minutes.

but keep in mind that you must really want to execute these steps, be sufficiently motivated to perform them. which means overcoming more unconscious resistance than you might ever have imagined. because there are many immediate “advantages” of anger that can interfere with your resolve, i’ll suggest a few of them that might interfere with your employing this powerful method to rid yourself of counter-productive anger.
