How many neutrons does the following nuclide have? 253/100 fm a. 253 b. 100 c. 153 d. none of these

Answer : The correct option is, (C) 153

Explanation :

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons.

Number of neutrons = Mass number - Number of protons

or,

Number of neutrons = Mass number - Atomic number

As we are given that:

The given nuclide is,

'Fm' is the fermium element.

Mass number of 'Fm' = 253

Atomic number f 'Fm' = 100

Now we have to determine the number of neutrons.

Number of neutrons = Mass number - Atomic number

Number of neutrons = 253 - 100

Number of neutrons = 153

Therefore, the number of neutrons in the 'Fm' nuclide have 153.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

your answer is c) plasma
