Question

Using complete sentences, answer the questions below. please help!

I need the answers before 11:59.

1)Describe the structure of atoms, including locations and charges of protons, neutrons, and electrons.

2) Five friends looked at a piece of aluminum foil. They wondered what they would see if they could see inside an atom of aluminum.

This is what they said:

Jeb: I think it would look like a tiny, dense ball with tiny particles tightly packed inside it.

Jane: I think there would be a tiny, dense center surrounded by a lot of empty space where some particles are whizzing around.

Hal: I think there would be a large center made up mostly of empty space with particles whizzing around in it. It would be surrounded by a dense shell.

Pick the friend that you agree with and explain why you agree. Be sure to include the friends' name and factual information to back up your explanation.

Answer 1

An atom is the smallest known unit and it is present in all the matter. The space occupied by atom is divided into two components: the nucleus and orbitals. The nucleus is the center of the atom, and orbitals surround the nucleus.

Location of protons-

Protons are positively charged particles within atoms. Each atom has at least one proton. The number of protons determine the identity of an atom.Protons reside in the nucleus of the atom.

Location of Electron-

Electrons travel around the nucleus in the orbital. Electrons are negatively charged particles. In a neutral atom, the number of electrons and protons are same. Though they are much smaller than protons but have the same strength charge.

Location of Neutrons-

Neutrons are located with protons in the nucleus. They have no charge and have the same mass as protons. Not all atoms have neutrons, and the number of neutrons is not usually the same as protons or electrons.

Part B-

I agree with Jane's statement as an aluminium atom has a dense central nucleus surrounded by negatively charged electrons, The protons and neutrons are closely packed in the center an 13 electrons are surrounding this center.
