QuestionHow many neutrons are in a Cerium atom with an atomic mass of 140?

Studdy Solution

STEP 1

Assumptions1. The atomic number of Cerium (Ce) is58. . The atomic mass of Cerium (Ce) is140.
3. The number of neutrons in an atom is calculated by subtracting the atomic number from the atomic mass.

STEP 2

First, we need to find the number of neutrons in an atom of Cerium. We can do this by subtracting the atomic number from the atomic mass.
$Number\, of\, neutrons = Atomic\, mass - Atomic\, number$

STEP 3

Now, plug in the given values for the atomic mass and atomic number of Cerium to calculate the number of neutrons.
$Number\, of\, neutrons =140 -58$

STEP 4

Calculate the number of neutrons in an atom of Cerium.
$Number\, of\, neutrons =140 -58 =82$ An atom of Cerium has82 neutrons in its nucleus.
