Answer:

Phosphorus

Explanation:

In given diagram there are 15 electrons are present. Which means it is orbital diagram of phosphorus.

The atomic number of phosphorus = 15

Number of electrons = 15

Electronic configuration of phosphorus:

P₁₅ = 1s² 2s² 2p⁶ 3s² 3p³

All other options are incorrect because:

Calcium have 20 electrons.

Electronic configuration of Ca:

Ca₂₀ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s²

Hydrogen have one electron.

Electronic configuration of H.

H₁  = 1s¹

Magnesium have 12 electrons:

Electronic configuration of Mg:

Mg₁₂ = 1s² 2s² 2p⁶ 3s²

An ideal gas is a theoretical gas composed of many randomly transferring factor particles that aren't difficult to interparticle interactions. the best gasoline idea is beneficial because it obeys the precise gas law, a simplified equation of country, and is amenable to evaluation under statistical mechanics.

An ideal gas is described as one for which both the extent of molecules and forces between the molecules are so small that they have got no effect at the behavior of the gas. The real gas that acts almost like a really perfect gasoline is helium. that is due to the fact helium, in contrast to maximum gases, exists as an unmarried atom, which makes the van der Waals dispersion forces as low as viable

Using the ideal gas equation:-

Given;

P₁ = 1 atm

V₁ = 100  L

n = 3

r = 8.314

T = PV/nR

  = 1 × 100 / 3 × 8.314

 = 4 K

Using your understanding about the patterns between vaporization and condensation, explain why the boiling point and the condens
eimsori [14]

Answer:

Vaporization and Condensation When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase.
