120

Explanation:

atomic number of Mercury is 80; therefore, each atom has 80 each of protons and electrons. The number of neutrons depends on the isotope, but for Hg-200, the number of neutrons is 200 - 80 = 120.

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.

geosphere and hydrosphere.
