Answer: Option (D) is the correct answer.
Explanation:
Vapor pressure is defined as the pressure exerted by the vapors which are present on the surface of a liquid.
For example, vapor pressure of water at room temperature is 0.0313 atm.
On the other hand, the temperature at which the vapor pressure of a liquid equals atmospheric pressure is known as boiling point.
For example, boiling point of water at room temperature is .
Thus, we can conclude that vapor pressure can be described as the pressure exerted by a gas above the surface of its liquid.
Answer :
(a) The charge and full ground-state electron configuration of the monatomic ion is, (+1) and
(b) The charge and full ground-state electron configuration of the monatomic ion is, (-3) and
(c) The charge and full ground-state electron configuration of the monatomic ion is, (-1) and
Explanation :
For the neutral atom, the number of protons and electrons are equal. But, they are unequal when the atoms present in the form of ions or the atom has some charges.
When an unequal number of electrons and protons then it leads to the formation of ionic species.
Ion : An ion is formed when an atom looses or gains electron.
When an atom looses electrons, it will form a positive ion known as cation.
When an atom gains electrons, it will form a negative ion known as anion.
(a) The given element is, Rb (Rubidium)
As we know that the rubidium element belongs to group 1 and the atomic number is, 37
