Answer:
Proton - Positive charge
Neutron - No charge
Electron - negative charge
Explanation:
An atom is the smallest particle of matter that takes part in a chemical reaction.
It is made up of three fundamental subatomic particles.
- Protons are the positively charged particles in an atom.
- Neutrons do not carry any charges and are neutral
- Electrons are negatively charged
Both the protons and neutrons occupy a tiny center where the mass of the atom is concentrated. The region is called the nucleus.
Your answer is B. Rust does not rust.
Naming conventions for 2 non-metals like Si and O are based on their valence electrons, Si has 4 electrons around it and Oxygen has 6, in order for you to satisfy octet (8 electrons around each element) surrounding each Si and O, you need another O, To name these 2, just write the name of the first element which has less electrons first then the second element to which you use a prefix "di" since it means there are two oxygen, then put the names together and end the name of the second element with "ide" (remove the last 4 letters).
Silicon + "dI" + ox +"ide"
