#### Number of Protons in the Nucleus of an Atom

Atoms are the small particles of which every element is made up of. The atom possesses the properties of its element.

Binary system is actually a numerical system which uses only 2 symbols, 0 and 1. Because of its simple implementation in Electronic digital circuitry making use of logic gates, all contemporary computers make use of the binary system internally.

**Listed below are some standard conversions among binary values and decimal values.**

**Refrence**

decimal 0 = 0 in binary

decimal 1 = 1 in binary

decimal 2 = 10 in binary

decimal 3 = 2 + 1 = 11 in binary

decimal 4 = 22 = 100 in binary

decimal 7 = 22 + 2 + 1 = 111 in binary

decimal 8 = 23 = 1000 in binary

decimal 10 = 23 + 2 = 1010 in binary

decimal 16 = 24 = 10000 in binary

decimal 20 = 24 + 22 = 10100 in binary

The adding of binaries is comparable to the decimal system. The sole difference would be to carry over whenever the result is 2.

0 + 0 = 0

0 + 1 = 1

1 + 0 = 1

1 + 1 = 0, carry 1 = 10

For example:

0 1 1 0 1

+ 1 0 1 1 1

---------------------

= 1 0 0 1 0 0

Subtraction works similarly:

0 - 0 = 0

0 - 1 = 1, borrow 1 = -1

1 - 0 = 1

1 - 1 = 0

For example:

1 0 1 1 1

+ 0 1 1 0 1

---------------------

= 0 1 0 1 0
