Question

Complete the reaction

₇N¹⁴ + ₀n¹ → ..... + ₁H¹

1. ₆C¹⁴
2. ₆C¹³
3. ₆C₁₂
4. ₇N₁₅

Answer 1

Correct Answer - Option 1 : ₆C¹⁴

Concept:

Positron	Positrons are ejected when a proton is converted into a neutron. The ejection of positron lowers the atomic number by one unit but leaves the mass number unchanged.
Anti-neutrino	Antineutrinos are ejected when a neutron is converted into a proton. A beta particle is also created in this process. The net equation can be written as  1n0 → 1p1 + 0e-1 + 0ν0 It is represented by β +.
Alpha	Alpha particles charge is 2e - and mass is 4 times that of hydrogen. When an alpha particle is ejected from the nucleus the element loses 2 units in atomic number and 4 units in mass number.
Beta	Beta particles have a charge equal to that of an electron. Ejection of a beta particle changes the atomic number by plus one but no change in mass number occurs.
Gamma	Gamma Rays do not have any charge of or mass.

Explanation:

• The reaction given is

₇N¹⁴ + ₀n¹ → ..... + ₁H¹.

• Before the reaction, the total mass was

\(14 + 1 = 15\)

• The total no of electrons were 

\(14 + 1 = 15\)

• After the reaction, one Hydrogen is produced.
• To maintain the no of electrons, an atom with 6 electrons and mass = 14 must be produced.

So, the element produced is ₆C¹⁴.

In the atmosphere, ₆C¹⁴ is produced by the same reaction.
