E

The missing element  : ₇¹⁴N

Given

Reaction

₆¹⁴C ⇒X + ₋₁⁰e

Required

The missing element

Solution

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

In a decay reaction, the sum of the mass number and atomic number before and after the decay is the same.

The element X :

Atomic number = 6 + 1 =7

Mass number = 14 + 0 = 14

they are made of gases.

they have a spherical shape.

they make energy through fusion.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
