The emission wavelength of the atoms excited above the ground state is 599.8 nm.
<h3>Emission wavelength of the atoms</h3>
The emission wavelength of the atom is determined by using the following formulas as shown below;
E = hf
E = hc/λ
where;
- E is the energy of the atom
- h is Planck's constant
- c is speed of light
- λ is the emission wavelength
λ = hc/E
λ = (6.626 x 10⁻³⁴ x 3 x 10⁸) / (3.314 x 10⁻¹⁹)
λ = 5.998 x 10⁻⁷ m
λ = 599.8 x 10⁻⁹ m
λ = 599.8 nm
Thus, the emission wavelength of the atoms is 599.8 nm.

Explanation:
In the nuclear symbol of an element, the superscript represents the mass number. The mass number is the sum of the number of protons and the number of neutrons present in the atom. The subscript is the atomic number which is the number of protons present in the atom or the number of electrons in the neutral atom.
Answer:
An element is made of one type of atom, while a compound is two or
more types of atoms combined.
Explanation:
An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.
Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.
- There are over a hundred elements known to date.
- Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek
- Examples are copper, gold, iron
- The properties of a compound are distinct and different from those of the individual elements that are combined in its make up.
- There are several millions of compounds known.
- They are usually represented by chemical formulae.
As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.
what is that????????????????
As volume increases, the temperature will increase.
As volume decreases, the temperature will decrease.
