Answer;
From highest to lowest is Li>Na>K>Rb.
Explanation;
- Ionization energy is the energy that is required to dislodge or remove an electron from the outer most energy level or energy shell. The first ionization energy is the energy required to remove the first electrons from the outermost energy shell.
- Lithium will have the highest first ionization energy, as the outer electron is closer to the pull of the nucleus and not shielded by full shells. This means that rubidium will be the lowest.

after a volcanic eruption is the answer
Mudflows of volcanic eruptions are the most dangerous, and are called lahars
Answer:
C. Molecules or ions of a solute spread throughout the water molecules.
Explanation:
C. Molecules or ions of a solute spread throughout the water molecules.
This Metal belongs to Group I (Alkali Metals).
Alkali Metals present in Group I are considered as the most reactive metals in periodic table. There reactivity increases tremendously down the group. The reactivity is mainly due to less ionization energies. Therefore, going from top to bottom along the group the ionization energies decreases hence, increasing there reactivity respectively.
Alkali metals when reacted with water undergoes an exothermic reaction resulting the formation of corresponding metal hydroxide and hydrogen gas i.e.
2 M + 2 H₂O → 2 MOH + H₂
Also, these metals are in solid state at room temperature (i.e. 25 °C) and their boiling points are as follow,
Lithium = 180.5 °C
Sodium = 97.79 °C
Potassium = 63.5 °C
Rubidium = 39.48 °C
Cesium = 28.44 °C
3.28 x 10³ mol of water has a mass of 59.1156 kg. This is the accurate answer to the given question.
We can use the molar mass of water, which is 18.02 g/mol, to calculate the mass of 3.28 x 10³ moles of H2O. The following equation can be used to translate the quantity of moles into grams:
mass is determined by multiplying the number of moles by the molar mass.
Inputting the values provided yields:
18.02 g/mol times 3.28 x 10 3 moles of mass equals 59,115.6 g.
Lastly, by dividing by 1000, we can change the mass from grams to kilograms:
mass is 59,115.6 grams per kilogram (59.1156 kg).
As a result, 3.28 x 10³ moles of H2O have a mass of 59.1156 kg.

The first element of the periodic table is hydrogen (H), and the second element is helium (He).
Hydrogen, with atomic number 1, is the first element in the periodic table. It is the lightest and the most abundant element in universe. Hydrogen is a colorless, odorless gas and is the building block for all other elements.
Helium, with atomic number 2, is the second element in the periodic table. It is also a gas, but unlike hydrogen, it is inert and does not readily react with other elements. Helium is known for its low density, which makes it lighter than air, and it is commonly used for filling balloons and as a cooling medium in various scientific and industrial applications.
So, the first element of the periodic table is hydrogen (H), and the second element is helium (He).
