Helium decays to form lithium. 6 2 he → 6 3 li 0 -1 e this type of nuclear decay is called .
PSYCHO15rus [73]

To understand this question, we need some knowledge on radioactive decay. This type of nuclear decay is called a beta decay

<h3>Beta Decay</h3>

This is the process where a radioactive material is fired or naturally emits a beta particle which is equivalent to the lose of an electron and spontaneously becomes an entirely different element.

^6_2He \to ^6_3 Li + ^0_-_1e

The participating actors in this nuclear reaction are

  • helium
  • lithium
  • electron

This is the decay process of helium particle in which it became a lithium particle and emitted an electron in the process.

Find the mean of the integers
mrs_skeptik [129]

We need to find mean of given integers.

We have -16,39,-10,-16,12,31.

In order to find mean, we need to add all the given inetgers.

Therefore, putting plus sign in between integers.

-16+ 39+ (-10)+(-16)+12+31 .

We will add all positive number 39+12+31 = 82

We will add all negative numbers by negative numbers, -16-10-16 = -42.

Therefore,  -16+ 39+ (-10)+(-16)+12+31  = 82 - 42 = 40.

We have given total 6 integers.

So, in order to find the mean, we need to apply following formula

Mean = \frac{Sum \ of \ all \ number }{Total \ numbers}

We get,

Mean = 40/6 = 6.66666......

We can round it to 6.67.

Therefore, mean of the given integers = 6.67 (approximately) .
