Can you please answer this question and explain all of the steps

Answer the following question:

Which of the following is not a fundamental subatomic particle that forms elements? Which of the following is not a fundamental subatomic particle that forms elements? electrons protons nucleus neutrons

Silver (Ag) atoms contain fewer electrons, neutrons and protons than Gold (Au) atoms. To change Silver into Gold, a chemist might try to add nucleus, because these particles are the ones that to the determine the identity of an atom. protons and electrons neutrons electrons neutrons and electrons protons

draw the hydrogen bonds for the following nucleic acid base pair: G and C

What if there are a different number of Neutrons? Sometimes elements have a different number of neutrons than usual, so therefore have a different atomic mass. This is what we call an Isotope (a variant form of an element which has the same number of protons but a differing number of neutrons). Sometimes we’ll see Isotopes labeled with their new mass like this: 14C = this is Carbon 14. Notice it has a different mass than what is on your periodic table The average mass of all the isotopes is defined as an element’s Atomic Weight. Can you answer questions about these Isotopes?

What is the total number of valence electrons in CO 2?     14     16     19     20     24

The slight positive charge of a hydrogen atom in one water molecule is drawn to the slight negative charge of an oxygen atom in another. This interaction is known as a(n)
