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.

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.

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.

Answer:

Plate tetonics theory is the idea that different tectonic plates, are constantly moving and changing the surface of our Earth. They can move in three ways, convergent, divergent, and transform. Seafloor Spreading is like an example of divergent movement. When the plates diverge from each other it can create various changes such as creating a new sea floor. You can use seafloor spreading as an example of the plate tetonics theory.

Heat can travel from one place to another in three ways: Conduction, Convection and Radiation.

The layer of Earth which provide transfer from the white core to the lithosphere that fuels convection is the mantle.

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.

The average atomic mass of element X that has two isotopes (one of 45.0 amu mass and 45% abundance and the other of 47.0 amu mass and 55.0% abundance) is 46.1 amu (option 1).  

The average atomic mass (A) of element X can be calculated as follows:

[tex] A = m_{1}\%_{1} + m_{1}\%_{1} [/tex]    (1)

Where:

m₁: is the mass of isotope 1 = 45.0 amu

m₂: is the mass of isotope 2 = 47.0 amu

%₁: is the abundance percent of isotope 1 = 45.0 %

%₂: is the abundance percent of isotope 1 = 55.0 %

Hence, the average atomic mass is (eq 1):

[tex] A = m_{1}\%_{1} + m_{1}\%_{1} = 45.0 amu*45.0\% + 47.0 amu*55.0\% = 45.0 amu*0.45 + 47.0 amu*0.55 = 46.1 amu [/tex]  

Therefore, the average atomic mass of element X is 46.1 amu (option 1).
