Question

Rounded to the nearest whole number, how many neutrons, on average, are in an atom of osmium? 76 114 190 266

Answer 1

Osmium has 114 neutrons on average

Answer 2

Answer: The number of neutrons in osmium is 114.

Explanation:

Atomic number is defined as the number of protons that are present in an atom. It is represented as 'Z'

Atomic number = Number of protons

Mass number is defined as the sum of number of protons and number of neutrons that are present in an atom. It is represented as 'A'

Mass number = Number of neutrons + Number of protons

We know that:

Atomic number of osmium = 76

Mass number of osmium = 190

Number of neutrons = 190 - 76 = 114

Hence, the number of neutrons in osmium is 114.
