Mumz [18]3 years ago
6 0

Answer:

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.

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
