Atoms of the same element can have different atomic masses because they can have different numbers of A electrons B neutrinos C neutrons D protons

C neutrons

Explanation:

Elements can have isotopes, which are atoms with different atomic masses. They have the same number of protons but different number of neutrons.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
