Which part of the atomic model below would be most useful for identifying the chemical properties of the atom? A. The number of protons in the nucleus.
B. The number of electrons in the electron cloud.
C. The number of valence electrons in the electron cloud.
D. The atomic mass of the atom.

c is the answer because when something is left after something evaporates that shows the chemical change.

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.

the answer is c.the valence of the atoms combine .

d
