How many neutrons does element x have if its atomic number is 24 and its mass number is 75?

The answer is: the element have 51 neutrons.

The atomic mass number of an element is equal to the sum of the number of protons and neutrons, also we need to remember that the atomic number is equal to the proton number.

So, to calculate how many neutrons does the element have, we need to write the following equation:

Where:

Hence,

So, the element have 51 neutrons.

Have a nice day!

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
