Enter the expression 147n α, where α is the lowercase greek letter alpha

Core reactions that occur:

¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H

Can be written :

¹⁴₇N (α, H) ¹⁷₈O  , α = ⁴₂He

Fusion and fission reactions are reactions involving atomic nucleus reactions

Fission reaction is a nucleation division reaction by firing a particle usually neutron so that it gets smaller particles of atomic nuclei.

A fusion reaction is a combining reaction of 2 atomic nuclei. Usually what is often used is a reaction between the hydrogen isotope that will form Helium

At the core, the reaction applies the law of eternity

the energy before and after the reaction is the same

the number of atomic numbers before and after the same

the number of mass numbers before and after the same

Particles that play a role in core reactions include

In general, the core reaction equation can be written:

X = target core

a = particle fired

Y = new core

b = the particle produced

Q = heat energy

or can be written simply

In the ¹⁴₇N atomic nucleus, a fusion reaction occurs with ⁴₂He which produces isotopes of Oxygen and ¹₁H protons.

¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H

This reaction can be written down

¹⁴₇N (α, H) ¹⁷₈O

i'm assuming that the correct answer is indeed the first one/ "a"..
