answer both parts of this essay question:
a) (5pts) describe the mass, charge, and location of protons, neutrons, and electrons
in an atom.
b) (6pts) how do protons, neutrons, and electrons determine the properties of an
atom (what is the role of each particle)?

(A) protons and neutrons both have a mass of 1 amu and are found in the nucleus. However, protons have a charge of positive 1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of negative 1.

(B)    The number of electrons, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element. Electrons have a negative charge

Explanation:

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."
