Which is not unique to each element? a. proton number b. atomic number c. neutron number d. chemical symbol

The correct answer is Option C.

Explanation:

Atomic number is defined as the number of protons or number of electrons present in a neutral atom. It is represented as Z.

Z = Atomic number = Number of electrons = Number of protons

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

A = Mass number = Number of protons + Number of neutrons

For Example: Taking potassium and calcium elements

Number of protons in potassium element = 19

Number of neutrons in potassium element = 20

Number of electrons in potassium element = 19

Number of protons in calcium element = 20

Number of neutrons in calcium element = 20

Number of electrons in calcium element = 20

Neutron number can be same for any two elements.

Hence, the correct answer is Option C.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
