Which of the following is the correct way to find the number of neutrons in an element? A. add protons and neutrons

B. subtract atomic mass from atomic number

C. subtract atomic number from atomic mass

D. add atomic mass and atomic number

The Answer is B: subtract atomic mass from atomic number. I remember doing this in 8th grade!!!:)

Explanation:

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom and the atomic number.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

is there any options? maybe im just not seeing them but i need the options to
