What is the<br> total charge of 1 proton, 1 electron, and 1 neutron?
iragen [17]

Given parameters:

Number of protons  = 1

Number of electrons = 1

Number of neutrons  = 1

unknown:

Total charge = ?

Atoms are made up of elementary particles of protons neutrons and electrons.

Protons are the positively charged particles in an atom

Electrons are the negatively charged particles

Neutrons do not carry any charges

To find the total charge on an atom; simply find the difference between the number of protons and electrons.

       Total charge  = Number of protons - number of electrons

                               = 1 - 1

       Total charge is 0

Therefore, the total charge is zero, 0

Ganezh [65]

Answer: option B. - A, B, D, E, C, H, F, G is correct using the principle of cross-cutting relationships.

The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through.

Explanation:

The full sequence of events is:

1. Layer A formed.

2. Layer B formed

3. Layer D formed.

4. Layer E formed

5. After layers A-B-D-E were present, intrusion C cut across all three.

6. Fault H formed, shifting rocks E through A and intrusion C.

7. Weathering and erosion created a layer of soil on top of layer F then G.
