when hydrogen atom absorbs a photon, and an electron moves level 1 to level 2, what happens to the energy of the atom?

Answers

Answer:

When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon).

What element is in period 6 with 2 valence electrons?

Answers

Answer:

Barium

Explanation:

I think that's the answer

The element in period 6 with 2 valence electrons is Barium.

The periodic table has been organized into periods and groups. The period is in an horizontal arrangement while group is vertical arrangement.

The elements that can be found in period 6 are Beryllium, Magnesium, Calcium, Strontium, Barium etc.

Elements in the same group have the same number of valence electrons. This means that elements in group 2 have 2 valence electrons.

Barium possess two valence electrons because it is in group 2 and it is also in period 6. Therefore, the element in period 6 with 2 valence electrons is Barium.

When an egg is boiled in a pot of water on the stove, there is more than one kind of heat transfer. Heat is transferred from the stove to the pot directly since they are physically touching. Heat is also transferred from the pot to the egg, carried through the water.

Answers

Answer:

Stove → Pot = conduction, Pot → Egg = convection.

Explanation:

There are three ways in which heat is being transferred from one medium to the other and the means are; radiation, conduction and convection heat transfer.

Radiation is the process in which heat is being transferred through emission in form of electromagnetism. Conduction heat transfer Is the process in which heat is being transferred through contact that is two bodies touching each other. Convection heat transfer is the kind of heat that happens through gases.

Since the heat from the stove touching the pot is the conduction heat transfer.

After the water has been heated up, the gas from the water makes the convection heat transfer.

Which of the following elements is the least reactive metal? Sodium, Rubidium, Chlorine, and Magnesium.​

Answers

First off chlorine is not a metal so you can ignore that one.

Sodium and Rubidium are in group 1 of the periodic table and Magnesium is in group 2.

Group one metals are more reactive than group two because it is harder for the group two metals to lose their 2 valence (outer most) electrons.

As you go down group 1 there is an increase in the reactivity this is because as you go down there is an increase in the atomic radius which leads to more shielding. This weakens the electrostatic forces of attraction making it easier to lose the outermost electrons, therefore they are more reactive.

Magnesium

Is iron rusting a chemical reaction? Explain why or why not.

Answers

Answer: Yes- Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.
