<u>Answer:</u> The number of neutrons in boron are 6.
<u>Explanation:</u>
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and number of neutrons present in an atom.
Mass number = Number of neutrons + Number of protons.
We are given:
Mass number = 11
Atomic number of boron = 5
Number of neutrons = Mass number - Atomic number = 11 - 5 = 6
Hence, the number of neutrons in boron are 6.

Answer: 20%
Explanation:
Relative error = Absolute error/actual value
= 0.1/0.5
= 0.2
Hence,
Minimum % Relative error = 0.2 ×100%
= 20%
