Hydrogen H

Answer 2

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)

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

Step-by-step explanation:

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:

• Option A: 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

• Option B: 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

• Option C: 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

• Option D: 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)
