Answer:
"Energy Level" is the correct approach.
Explanation:
- An electric charge electron density during an atomic seems to be the potential condition for this with the electron and therefore is proportional to its density from the nucleus. The ground state seems to be a particle, nucleus, and perhaps molecule with the corresponding energy level as well as its electrodes.
- The electron travels to something like a higher or excited energy state whenever there's an improvement in electricity, and has also been stimulated.
Answer:
The periodic table tells you the atomic number (which tells you the number of protons and electrons). It also includes the mass number, which is the sum of the protons and neutrons in the nucleus of an atom.
Answer:
<h3>Reactivity is the ability of matter to react chemically with other substances. Flammability is the ability of matter to burn.</h3>
Well on the periodic table Cl is in the section saying it is a non metal. In addition, it is nonmetls because it is usually a gas while metals are not. Finally, it is a non metal because it usually gains electrons instead of losing them during a reaction unlike metals.
