The atomic number or (also called) the proton number, represents the number of protons, which also represents the number of electrons in that single atom itself (an atom which has not gone through reactions of any kind will have the same number of electrons as number of protons).

Hope this helps! :)

P.s. This question seems more of a Chemistry than Biology question in my opinion

What blood types are possible for a child whose parents both have AB blood type?
erma4kov [3.2K]

Answer:

-blood type a

-blood type b

-SOMETIMES type o but very rarely.

Explanation:

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. While a child could have the same blood type as one of his/her parents, it doesn't always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B.
