Help please ill give 100 points

Answer:

SCORE WARNING ! ! ! (JUST FINISHED MY TEST AND GOT A B IM NOT SURE WHICH ONE WAS INCORRECT btw it was the K12 8th grade test)

1. C / Proton (p+)

2. D / the number of protons and neutrons in an atom (p + n)

3. B / the number of protons

4. D / a molecule

5. B / becomes moldy quickly

6. D / gases

7. D / A physical change is a change from one state of matter to another; a chemical change results in a new substance formed.

8. D / upper right side

9. B / group

10. B / atomic number (# of protons)

Explanation:

I just took the test

The positively charged subatomic particles are called protons. The mass number of an atom is the sum of number of protons and neutrons and the atomic number is the number of protons.

An atom is the basic unit every substances. It is made up of subatomic particles electrons, protons and neutrons. The positively charged particles are called protons. Whereas electrons are negatively charged.

The atomic number is the number of protons and the mass number indicates the sum of number of protons and neutrons.

Water can be classified as a diatomic molecule formed from two hydrogens and one oxygen atom. Among the given, malleability is a physical property. It is the ability to change the shape and size of metal blocks.

Liquids has definite volume but does not have a defined shape. They assume shape of the container.A physical change is a change from one state of matter to another; a chemical change results in a new substance formed.

Nonmetals are located in the side upper right side of periodic table. Metals are covered in left and middle portion. The elements F, Cl are in same group. All the elements are arranged in periodic table based on their atomic number.
