Answer:
the NaCl is not considered a molecula
Explanation:
Sodium atoms, (Na +) and chlorine atoms, (Cl-) form a three-dimensional network. The cations and the anions are joined together by electrostatic attraction which we call ionic bonding
Molecules are atoms bound with chemical bond.
Answer:
The number of protons in an atom is different than the atom’s total mass.
Explanation:
Mendeleev knew only that, with some anomalies, the properties of elements varied periodically with their atomic masses.
Moseley's X-ray experiments enabled him to remove these anomalies and to show that the properties of elements varied with their atomic numbers.
Chadwick later discovered that the mass differences were caused by the presence of neutrons.
Answer:
you can use the idea of molecular masses to calculate easily
Answer:
Tempature is the measurment of how heat travels through a substance
