How many protons,electrons and neutrons are in a neutral atom with an atomic number of 35 and an atomic mass number of 81 contains?

the number of protons is 35 because the number of protons is equal to the atomic number which is equal to the number of electrons hence no need to waste your time on that.

Neutrons is the atomic mass - protons

81-35=46.

From my above explanation the number of electrons is equal to 35.

Explanation:

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
