Which scenario BEST describes how an atom produces light?

Chemistry
1 answer:
oksian1 [2.3K]3 years ago
7 0

Answer:

electron loses energy as it transitions to lower energy level

Explanation:

An atom is capable of absorbing and releasing electrons. The atom of a substance is said to be at its GROUND LEVEL STATE when it contains the lowest energy level. However, when it absorbs or takes in energy, it moves to a high energy level called EXCITED STATE. This level is unstable and hence, subject to declination.

Due to the instability of the excited state of an atom, it tends to lose the absorbed electrons and in the process of doing so, it emits or produce light. Therefore, according to this question, light is produced by an atom when the electron loses energy as it transitions to lower energy level i.e excited state to ground level state.

An equal number of moles of KI (potassium iodide) and MgI2 (magnesium iodide) are dissolved in equal volumes of water.
SOVA2 [1]
<span>  As we know that MgI2 (magnesium iodide) when dissociated it gives more ions than  the KI so it has more boiling point as its boiling point is high it means that it boils more so it has low vapor pressure and freezing point

On the other hand as we know that KI dissociates into two  ions so so it has high freezing and vapor pressure
hope it helps</span>

The mass number of an atom is 15, and its atomic number is 7. The atom probably has... 8 neutrons in the nucleus. about as much
Artist 52 [7]

Answer: Option (a) is the correct answer.

Explanation:

Atomic number is the sum of only total number of protons present in an element. Whereas mass number is the sum of total number of both protons and neutrons present in an element.

For example, given atom has mass number as 15 and its atomic number is 7.

Therefore, number of neutrons present in it will be calculated as follows.

                    Mass number = no. of protons + no. of neutrons

                         15 = 7 + no. of neutrons

                    no. of neutrons = 15 - 7

                                               = 8

Thus, we can conclude that the given atom contains 8 neutrons in the nucleus.
