The question is incomplete, here is the complete question:

Based on its location on the periodic table, which element would be most likely to form a positive ion?

A. Sulfur (S)

B. Chlorine (Cl)

C. Sodium (Na)

D. Fluorine (F)

<u>Answer:</u> The element which is most likely to form positive ion is Sodium (Na)

<u>Explanation:</u>

An ion is formed when a neutral atom looses or gains electrons

When an atom looses electrons, it results in the formation of positive ion known as cation.

When an atom gains electrons, it results in the formation of negative ion known as anion.

For the given options:

  • <u>Option A:</u> Sulfur

Sulfur is the 16th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^4

This element will gain 2 electrons to attain stable electronic configuration and will form S^{2-} ion

  • <u>Option B:</u> Chlorine

Chlorine is the 17th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^5

This element will gain 1 electron to attain stable electronic configuration and will form Cl^{-} ion

  • <u>Option C:</u> Sodium

Sodium is the 11th element of the periodic table having electronic configuration of 1s^22s^22p^63s^1

This element will loose 1 electron to attain stable electronic configuration and will form Na^{+} ion

  • <u>Option D:</u> Fluorine

Fluorine is the 9th element of the periodic table having electronic configuration of 1s^22s^22p^5

This element will gain 1 electron to attain stable electronic configuration and will form F^{-} ion

Hence, the element which is most likely to form positive ion is Sodium (Na)

bagirrra123 [75]

The riddle is solved by knowing that there is only one person left in the garden and that is you.

<h3>How many people are in the garden?</h3>

We are told that there were a total of 34 people in the yard. We do not know if these people are in the garden or somewhere around the yard. The next information we have is that a total of 30 persons were killed.

Since you killed them in the garden, the others may still be lurking somewhere in the yard thus there is only one person left in the garden and that is you.

A man wishes to pull a crate 15m across a rough floor by exerting a force of 100 N. The
Darina [25.2K]

Answer:

option (E) is correct.

Explanation:

Work done is defined as the product of force and the distance in the direction of force.

force, f = 100 N

Coefficient of friction, = 0.25

distance = 15 m

So, net force F = f - friction force

F = 100 - 0.25 x m g

Work = (100 - 0.25 mg) x d cosθ

For minimum work, the angle should be maximum.

So, the value of θ is 76°.

thus, option (E) is correct.
