If an element has an atomic number of 7 and an atomic mass number of 15, how many protons, neutrons, and electrons does it possess?
a) 7 protons, 8 neutrons, and 7 electrons
b) 7 protons, 8 neutrons, and 8 electrons
c) 8 protons, 7 neutrons, and 8 electrons
d) 15 protons, 8 neutrons, and 8 electrons
Solutions
Expert Solution
Number of electrons = Number of protons = Atomic number = 7
Number of neutrons = Mass number - atomic number = (15-7) = 8
Therefore, the correct answer is option a.

A hypothetical element Ec has an atomic number of 156 and an
atomic mass of 300.
1. How many neutrons and electrons would be found in a neutral
Ec atom?
2. If one proton were removed from Ec, would it still be the
same element?

it still be the same element? Would anything change about the
element?

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.
