Name the element with atomic number (Z) = 15 and atomic mass number = 31, Use the symbol, not the word.

How many electrons does the neutral atom of this element have? Use a number, not a word.

How many neutrons does the neutral atom of this element have? Use a number, not a word.

Solutions

Expert Solution

Element with atomic number (Z) = 15 and atomic mass number = 31 is Phosphorous, with symbol P

no of Electrons = no of protons = 15

no. of neutrons = atomic mass - atomic number = 31 - 15 = 16

Is Atomic Mass and Atomic Weight the same terms? Or is Atomic mass and Mass Number the same terms? On the MCAT Kaplan books it says that atomic mass and mass number are the same thing but online and other chemistry textbooks, atomic mass and atomic weight are the same thing. Can someone please clarify which two terms are the same thing or are they all different? I really need help to make sure I understand this for the MCAT.
