1) Across the period as one moves from left to right, atomic size decreases.

2) Consider 3rd period elements containing non-metal i.e Si, P, S and Cl.

3) Here, atomic radius of these elements are in following order Si>P>S>Cl.

4) However, electronegative of these elements increases as we move from left to right

5) Thus, the corresponding hydrides have higher electro-negativity difference,as one moves from left to right.

6) Due to this, bond polarity increases from left to right,

7) Increase in bond polarity, results in increasing proton donating capability.

8) Therefore, acidity increases as one moves along the period.

Why does a gold isotope, with an atomic number of 79, require more neutrons to be stable than a sodium isotope, with an atomic n
Leya [2.2K]

Here’s a simplified explanation.

The <em>protons</em> in the nucleus <em>repel each other</em>. The <em>neutrons provide the “glue”</em> that holds the nucleus together and prevents it from flying apart.

The “glue” is the strong nuclear force. It is strong but extremely short range. It falls off extremely rapidly as the p-n distance increases.

A <em>neon atom</em> has 10 protons. There are three stable isotopes, with 10, 11, and 12 neutrons.

With fewer than 10 protons, the glue is not strong enough to hold the nucleus together.

If there are more than 12 neutrons, the average p-n distance is great enough that the glue has again become too weak.

<em>Gold</em> has one stable isotope. It contains 79 protons and 118 neutrons.

If there are fewer than 118 neutrons, the proton repulsions will be too strong for the strong force. If there are more than 118 neutrons, the average p-n distance will be large enough that the glue will again be too weak to hold the nucleus toge ther.

I anm definitely not a halogen. But if all you knew about me
Dmitriy789 [7]

The periodic law is a law relating the properties of the element with their

atomic numbers.

The element is <u>potassium, K</u>.

Reason:

By atomic mass, potassium is 39.10 g, while argon is 39.10 g.

Going by the atomic mass alone, potassium should come before argon in

the periodic table and therefore should be an halogen and not an alkali

metal.

However, the number of protons in the potassium is 19, and therefore larger

than the number of protons in argon, which is argon.

Therefore, the element is <u>potassium, K</u>.
