When an excited electron in an atom moves to the ground state, the electron(1) absorbs energy as it moves to a higher energy state
(2) absorbs energy as it moves to a lower energy state
(3) emits energy as it moves to a higher energy :state
(4) emits energy as it moves to a lower energy state
Answers
Answer is: (4) emits energy as it moves to a lower energy state.
Atom emits a characteristic set of discrete wavelengths, according to its electronic energy levels.
Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state.
Each transition has a specific energy difference.
Each element's emission spectrum is unique.
When an excited electron in an atom moves to the ground state, the electron .
Further Explanation:
Electronic transition:
It is a process that occurs when an electron undergoes emission or absorption from one energy level to another energy level.
When an electron undergoes a transition from a lower energy level to a higher energy level then it requires energy to complete the process. This transition is an absorption process.
When an electron undergoes a transition from higher energy level to lower energy level then it emits energy to complete the process. This transition is an emission process.
An excited electron has higher energy than that present in the ground state of the atom. Energy is to be released when an excited electron returns to its ground state. Therefore the excited electron emits energy when it jumps from an excited state (higher energy state) to the ground state (lower energy state). Hence option (4) is the correct answer.

The correct answer is option D, that is, protons and neutrons.
The center of an atom is known as the nucleus, it comprises nucleons, that is, neutrons and protons, and is enveloped by the cloud of electrons. The nucleus exhibits the majority of the mass of the atom in spite of being a very small constituent of the atom. Approximately all the atom's mass is formed of the neutrons and protons in the nucleus with a very small donation from the orbiting electrons.

The three ways of magma formation are, decompression melting brought on by reducing pressure, 2) Flux melting brought on by introducing volatiles and 3) Heat-induced melting brought on by raising temperature.
What is magma?
Magma is the molten fluid in the earth crest which eventually forms the rocks.Here are the three main ways that rock behavior can move past the green solidus line and result in molten magma:
1) Decompression melting brought on by reducing pressure, 2) Flux melting brought on by introducing volatiles and 3) Heat-induced melting brought on by raising temperature.
Different temperatures cause minerals to melt, as demonstrated by the Bowen's reaction Series. The solidus border is more of a fuzzy zone than a clearly defined line since magma is a mixture of many minerals; some minerals melt while others remain solid.
Partially melting rocks have the same characteristics as real-world magmas, which often include solid, liquid, and volatile components.

Answer:
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
