Answer:
ano pong topik po yan
Put in order from smallest to largest radii:
1. AI, Na, CI, Ar, Mg
2. S, Te, Po, Se, O
3. Cl, Ca, S, P, Ga, Mg
4. F, CI, Br, I, At
Answer:
1. Ar, Cl, Al, Mg, Na
2. O, S, Se, Te, Po
Explanation:
Just remember the trends. From left to right, atomic radius decreases because proton increases and pulls electrons closer. From top to bottom, atomic radius increases because there are more electron shells.

under what circumstances can an atom emit a photon
Answer:
Here
Explanation:
When the atom absorbs energy, it can move to a higher energy state, or excited state. Under what circumstances can an atom emit a photon? A photon is emitted when an atom moves from an excited state to its ground state or to a lower-energy excited state.
The mass lost by the positive electron should equal the mass gained by the negative electrode suggest two reasons why the results were not expected.
Answer:
The gain in mass by the negative electrode is the same as the loss in mass by the positive electrode. So the copper deposited on the negative electrode must be the same copper ions that are lost from the positive electrode.
