Chemical Property(s):
Toxicity.
Reactivity.
Types of chemical bonds formed.
Coordination number.
Oxidation states.
Flammability.
Heat of combustion.
Enthalpy of formation.
I know these are chemical properties because they are all a result of a chemical change. Chemical changes change the form of an object. For example, diluting orange juice by adding water changes it's ph from an acid to almost neutral.
Hope this helps!

Answer:
Lithium-7
Explanation:
By carefully inspecting the diagram we can see three different sub-particles.
1) Electrons (-vely charged, outside the nucleus)
2) Protons (+vely charged, Inside nucleus)
3) Neutrons (uncharged, Inside nucleus)
Mass Number:
Mass number is the number of protons and neutrons present in the nucleus of an atom.
Therefore, in our problem there are 4 neutrons and 3 protons.
So, the mass number is 7.
Atomic Number:
Atomic number is the number of protons present in the nucleus. This number shows the identity of an atom. If you go through the periodic table you will find that the atomic number 3 is for Lithium.
Result:
Lithium-7
