Question

Please help with questions 4 to 11 for 75 points!!! Thank you :D

Answer 1

Answer:

1 .Atom goes to C

2.Proton goes to A

3. Neutron goes to b

Question 4:Protons are a type of subatomic particle with a positive charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron

Question 5:Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. ... The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus.

Question6:Thomson's model of the atom in 1897 shows that the atom was a sphere of matter, wherein the electrons are mixed inside it. This model does not show the protons and the neurons. On the contrary, the current model that was proposed by Niels Bohr gives us a clearer representation of the structure of an atom.

Question 7:its mass number A is 23.

Question 8: 1 i found the number because hydrogen only has 1 atom so yuh..

I will answer the rest in the comennts:)
