history of the atom

Question 1

modles

Answer 1

a three-dimensional representation of a person or thing or of a proposed structure, typically on a smaller scale than the original.

Question 2

proton

Answer 2

A proton is a subatomic particle found in the nucleus of every atom. The particle has a positive electrical charge, equal and opposite to that of the electron.

Question 3

atom

Answer 3

An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is surrounded by one or more negatively charged electrons. The nucleus is positively charged and contains one or more relatively heavy particles known as protons and neutrons.

Question 4

neutron

Answer 4

A neutron is a subatomic particle found in the nucleus of every atom except that of simple hydrogen. The particle derives its name from the fact that it has no electrical charge; it is neutral. Neutrons are extremely dense

Question 5

electron

Answer 5

An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom – the other two are protons and neutrons.

Question 6

proton

Answer 6

is a tiny particle found in the neuclos

Question 7

thre parts of an atom

Answer 7

proton,nuetron,and the electrons
