What is the purpose of lewis dot diagrams? a. to show structural formula in which all subatomic particles are represented by dots; dot pairs or dashes b. to show structural formula in which valence protons are represented by dots; dot pairs or dashes c. to show structural formula in which valence electrons are represented by dots; dot pairs or dashes. d. to show structural formula in which valence neutrons are represented by dots; dot pairs or dashes

The purpose of Lewis dot diagrams, "To show structural formula in which valence electrons are represented by dots; dot pairs or dashes."

Explanation:

Lewis dot structure are the diagrammatic representation of the valence electrons of the atoms in the molecule. These lewis structure helps us in visualizing the valence electrons of the atom as well as the molecules whether they are in lone pairs or have bonds. The dot move around the outer elements of the molecule first unless they archive octet. The structure tells us about the connectivity of the compound. From this we can just check whether the element is available for bonding or not.

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.

that's what i got you can count the number of atoms
