Answer: Option (D) is the correct answer.

Explanation:

Electronegativity is defined as the ability of an element or atom to readily attract electrons towards itself.

Generally, non-metals are the species which tend to show electronegativity. Whereas metals have the ability to lose electrons in order to gain stability.

Hence, metals are electropositive in nature.

For example, potassium and francium are metals.

And, astatine is a metalloid, that is, it shows properties of both metals and non-metals. Hence, it shows both electropositive and electronegative nature.

Chlorine being a non-metal is electronegative in nature and hence, it has the ability to readily attract an electron.

Thus, we can conclude that out of the given options chlorine element is the most electronegative.

What is the electron configuration for<br> 08<br> 16
Elis [28]

The electron configuration for Oxygen : [He] 2s²2p⁴

<h3>Further explanation</h3>

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d, and f. The maximum number of electrons for each sub-shell is  

• s: 2 electrons  

• p: 6 electrons  

• d: 10 electrons and  

• f: 14 electrons  

Charging electrons in the sub-shell uses the following sequence:  

<em>1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.  </em>

The element is Oxgen, with symbol O, and :

the atomic number=8=number of electron

the atomic mass=16

The electron configuration based on the number of electrons(for Oxygen=8), so the configuration :

\tt _8^{16}O:1s^22s^22p^4 or we can write with noble gas [He] 2s²2p⁴

Help!!! I need the answer for "explain how using the periodic table can help answer this question"
Tanzania [10]
Well a compound is 2 or more different molecules together. So if you see a periodic table you will see the elements to see if they are the same or not.
