Together, the protons and neutrons are called what?A)nucleinucleons
B)nuclear binding C)energy
D)nuclear forces

Answers

Answer:The correct answer is 'nucleons'.

Explanation;

An atom is a structural unit of matter.It consist of three subatomic particles: electrons, protons, and neutrons.

Protons and neutrons are located at center of an atom where whole mass of an atom is concentrated that is in the nucleus of a atom.

Protons and neutron being located in nucleus are also known as nucleons.

Where as electrons revolve around the nucleus in different orbits inside an atom.

Hence, the correct answer is 'nucleons'.

What similarities do nuclear energy and chemical energy share?

Answers

atoms can be the source of both nuclear and chemical energy. Nuclear energy involves the atom's nucleus; chemical energy involves the atom's electrons—subatomic particles that surround the nucleus.

Both are types of potential energy, and Involve stored energy.  

Which of the following is a homogeneous mixture?a. iced tea
b. apple pie
c. orange juice
d. vegetable soup User: A group of students want to identify a sample of matter. They observed the sample and made the observations below. • There are various components in the sample. • Different regions of the sample have different properties. Based on these observations, how will the students classify the matter?
a. heterogeneous mixture
b. homogeneous mixture
c. chemical ...

Answers

The answer for the first question is A. Iced Tea and C. Orange Juice. The answer for the second question is A. Heterogeneous mixture

A homogeneous mixture is a combination of 2 or more substances wherein its concentration is evenly distributed throughout the mixture. This means that you cannot identify the different components or properties of the mixture. A heterogeneous mixture, on the other hand, is a combination of 2 or more substances wherein its components are unevenly distributed. This means that its components can visibly be identified from each other.
