Answer:
d
Explanation:
because nuclear charge ( no. of protons) increases
proton is the name for a nuclear particle that has about the same mass as a neutron, but with a positive charge.
The right answer is C.
Oxidation is the loss of electrons. A loss of electrons will appear as an increase in the positive charge of the element as it is converted to an ion. Here we have aluminum have an oxidation state equals zero as a reactant because it is in the element state. After reacting, it combines with three atoms chlorine where each chlorine atom usually has an oxidation state equals -1, therefore, we have -3 charges which have to be neutralized with the 3+ charges of aluminum.
AT, STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density
The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.
