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.
Which layer or layers of Earth provide the heat and energy that fuels convection?
The layer of Earth which provide transfer from the white core to the lithosphere that fuels convection is the mantle.
What is the Mantle layer?A mantle can be described as a layer inside a planetary body bounded above a crust and below a core. Mantles are composed of rock or ice and are usually the largest massive layer of the planetary body.
The mantle layer of the earth is a layer of silicate rock between the crust and the outer core. The mass of the mantle of 4.01 × 10²⁴ kg which is 67% of the mass of the Earth. It's a thickness of 2,900 kilometers making up about 84% of Earth's volume.
The mantle layer is predominantly solid, but it behaves as a viscous fluid. At mid-ocean ridges, partial melting of the mantle produces oceanic crust, and at subduction zones, partial melting of the mantle produces continental crust.
The temperatures range of the mantle from 200 °C at the upper boundary with the crust to 4,000 °C at the core-mantle boundary. The convection of the mantle is a chaotic process, the mantle transfers heat that fuels convection.

Answer:
Leaving a Copper penny in vinegar until it turns green
Explanation:
the others are physical changes. when copper penny is put in vinegar, a reactive oixde layer is formed which is green in colour. namely, Cu(II) acetate.
The green growing on the penny of copper and the rust forming on the nail of iron are chemical changes. Boiling away salt water, scraping iron filings from a mixture of sand with a magnet, and breaking a rock with a hammer, are physical changes.
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.
