Question

Consider the four atoms - L, M, N, and X with the given isotope symbols ( 124/47L, 116/48M, 124/50N, 114/50X ).

A) Which atom has the smallest mass number?
B) Which atoms have isotopes?
C) Which atom has the smallest number of electrons in the neutral atom?
D) Which atom has the largest number of neutrons?

Answer 1

Atom X has the smallest mass number, atoms L, N, and X have isotopes, atom M has the smallest number of electrons, and atom N has the largest number of neutrons.

Step-by-step explanation:

A) The atom with the smallest mass number is atom X, with a mass number of 114.

B) Atoms L, N, and X have isotopes.

C) The atom with the smallest number of electrons in the neutral atom is atom M, which has 48 electrons.

D) The atom with the largest number of neutrons is atom N, which has 74 neutrons.
