Question

Which of the following species gain electron more easily *
2 points
Na+
H+
Mg+
Hg+

Answer 1

Answer:

Among all the elements, hydrogen gains 1 electron to complete their duplet. Sodium (na), potassium (k), magnesium (mg) all losses their electron to attain stability as noble gas.

Answer 2

Answer:

H⁺ gain electron more easily to attain noble gas configuration.

Explanation:

• Hydrogen can gain one electron to become the hydride ion, which has a negative charge and the noble gas configuration of helium, which has two electrons in its lone electron shell.
• In the presence of strong bases, which are electron donors, hydrogen acts in this manner.

Is it easy for hydrogen to gain electrons?

• An electron can be gained or lost by a hydrogen atom. In its 1s orbital, it only possesses one electron. The greatest number of electrons in a s orbital is two.
• As a result, it can achieve noble gas configuration by gaining one electron.

Hydrogen- stability:

• By sharing an electron with another hydrogen atom, hydrogen becomes chemically stable.
• When two hydrogen atoms are combined with one oxygen atom, the chemical known as water is formed.
