Question

how many nuetrons are present in the nucleus of hydrogen atom can u say me whether its
a) 1
b) 2
c ) 3
d) 0​

Answer 1

Answer :

$\bigstar\:\underline{\boxed{\bf{\red{HYDROGEN:}}}}$

• Hydrogen is the lighest element.
• It has the simplest electronic configuration, 1s².
• Hydrogen resembles both alkali metals (loses one electron to form unipositive ion, form oxides, halides and sulphides) and halogens (forms diatomic molecule, hydrides and large number of covalent compounds).

✴ Isotopes of Hydrogen :

⇒ Protium ($\bf{_1H^1}$) has no neutron.

⇒ Deuterium ($\bf{_1H^2}$), also known as heavy hydrogen, has two neutrons.

⇒ Tritium ($\bf{_1H^3}$) which is radioactive and emits low energy β-particles, has three neutrons.

፨ The three isotopes of hydrogen have almost same chemical propertues but differ in their rates of reactions mainly due to their different enthalpy of bond dissociation.

✭ Option D is the correct answer.

Answer 2

Answer:

0

Explanation:

Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.
