Answer
Brief Explanations:
- The sub - atomic particle with a negative charge is an electron.
- A water molecule ($H_2O$) has 2 hydrogen atoms.
- The positively charged sub - atomic particle in the nucleus is a proton.
- The chemical element with atomic number 1 is hydrogen.
- When 2 or more molecules interact and change, it's a chemical reaction.
- The 4 fundamental states of matter are solid, liquid, gas and plasma. The tabular arrangement of elements is the periodic table.
- Metals are good conductors of electricity and heat.
- The central core of the atom with protons and neutrons is the nucleus.
- The sub - atomic particle without an electric charge is a neutron.
- The number of protons in an atom is the atomic number.
- The noble gases are in group 18 of the periodic table.
- A charged atom or molecule is an ion.
- The amount of matter in an object is mass.
- Organic chemistry deals with compounds containing carbon.
