Explanation:

In the nuclear symbol of an element, the superscript represents the mass number. The mass number is the sum of the number of protons and the number of neutrons present in the atom. The subscript is the atomic number which is the number of protons present in the atom or the number of electrons in the neutral atom.

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.
