Which of these statements correctly describe the atom? check all that apply. all matter on earth is made up of atoms. the subatomic particles of an element retain the properties of that element. the neutron has no charge and identifies the element. the electron is negatively charged and is located in a cloud surrounding the nucleus. the proton is positively charged and is found in the nucleus.

True: All matter on earth is made up of atoms.

False: Subatomic particles don't identify an element. I give you an electron. Can you tell me where it came from?

False: (1/2) A neutron has no charge [That's the True part]. It identifies the element. (Not true).

True: description of an electron.

True: description of a proton

All matter on Earth is made up of atoms.

The electron is negatively charged and is located in a cloud surrounding the nucleus.

The proton is positively charged and is found in the nucleus.

Explanation:

As we know that the atom is made up of three sub atomic particles give as

1). Electrons

2). Protons

3). Neutrons

Now we know that neutrons do not have any charge but it stays inside the nucleus and more than 50% of mass of the nucleus is due to neutrons.

Protons are of positive charge and it also stays inside the nucleus and number of protons inside the nucleus is same as atomic number.

Electrons are always of negative charge and it stays outside the nucleus in form of electron cloud and total negative charge of electron must be equal to total positive charge of proton in neutral atom.

the answer is b ) square root of 5

a and b sometimes have a positive value
