Answer:

the<u> atomic mass</u> of an element is the average mass of an element naturally occurring atom, or isotopes, taking into account the <u>percentage</u> of each isotopes​

Explanation:

The atomic mass of an element is obtained by obtaining the relative abundances (in percentages) of naturally occurring atoms and the masses of the isotopes. The atomic mass can also be defined as the sum of the protons and the neutrons in the nucleus of an element.

In the periodic table, the atomic mass is indicated below the symbol of each of the elements and is usually in the decimal form.

Liquids and solids are referred to as "condensed phases" because the attractive forces cause molecules to become stationary. lea
Savatey [412]

Answer:

leave little space between the molecules.

Explanation:

Matter is made up of small particles called molecules. These molecules present in matter are arranged inside its bulk.

In liquids and solids, the molecules are arranged very close together in such a way that there is only a little space between them. This is why liquids and solids are referred to as "condensed phases".

They are quite unlike gases where there is a lot of space between gas molecules.

What can you say about the strength of the intermolecular forces in neon and argon based on the critical points of Ne and Ar? (c
algol13

Explanation:

Since, it is given that critical temperature of Argon is 150.9 K and critical pressure of Argon is 48.0 atm.

It is known that gas phase of neon occurs at 50 K. As the boiling point of Ar is more than the boiling point of neon which means that there is strong intermolecular force of attraction between argon molecules as compared to neon molecules.

This is also because argon is larger in size. As a result, induced dipole-induced dipole forces leads to more strength in Ar as compared to Ne.

What is the energy per mole of photons, in kJ/mol, emitted by an argon ion laser which produces a green beam with a frequency of
Serga [27]

Answer:

Energy per mole of photons = 2.31 × 10^2 KJ/mol

Explanation:

Energy, E = hf;

Where h is Planck's constant = 6.63 ×10^-34, and f is frequency of the photons.

E = 6.63 × 10^-34 × 5.8 × 10^14

E = 3.84 × 10^-22 KiloJoules

I mole of photons contains Avogadro's number of particles, 6.02 × 10^23

Therefore, the energy per mile of photon is 3.84 × 10^-22 KJ × 6.02 × 10^23

Energy per mile of photon = 2.31 × 10^2 KJ/mol
