Will the valence electrons of calcium give or take away electrons?
The valence electrons of calcium will tend to give away electrons, as it is an alkaline earth metal with two valence electrons. This makes it more energetically favorable for calcium to lose these two electrons and achieve a full outer electron shell by forming a 2+ cation.
Will potassium share more properties with calcium or sodium?
Potassium will share more properties with sodium as they both belong to the same group (Group 1) in the periodic table. They both have similar chemical reactivity and form similar types of compounds. Calcium, on the other hand, belongs to Group 2 and exhibits different properties compared to potassium.
Which has more valence electrons atom or aluminum or phosphorus?
Aluminium has three valence electrons and phosphorous has five, hence the latter has more.
How many electrons does Ca lose to become more stable when bonding?
Calcium (Ca) typically loses 2 electrons to become more stable when bonding, as it has 2 valence electrons in its outer shell. By losing these electrons, calcium achieves a full octet, making it more stable.
How many electrons are gain or lost to form ions for calcium?
A calcium atom loses 2 electrons to form a Ca2+ ion. This is because calcium has 20 electrons in its neutral state, and it becomes more stable by losing these 2 outer electrons to achieve a full valence shell.

Why is it easier for strontium to lose valence electrons than calcium?
Strontium is larger in size compared to calcium due to more electron shells, making it easier for strontium to lose valence electrons farther from the nucleus. This results in weaker attraction between the valence electrons and the nucleus, leading to easier electron loss in strontium compared to calcium.
Which is more reactive Mg or Ca Why?
Calcium is more reactive. In the periodic table, Calcium is directly below Magnesium, which means that a calcium atom is larger than a magnesium atom. This means that the electrostatic attraction between the valence electrons of calcium and the nucleus is weaker than in magnesium(larger distance, smaller force). So, the valence electrons of calcium can easily be lost to form Ca2+ , which translates to Calcium being the more reactive metal.
Which is greater the second ionization energy of potassium or that of calcium?
The second ionization energy of calcium is greater than that of potassium. This is because calcium, with its higher nuclear charge and smaller atomic size compared to potassium, holds onto its electrons more tightly.
Why do you believe that the valence electrons of calcium and potassium reside in the 4s orbital rather than in the 3d orbital?
The 4s orbital is energetically lower than the 3d orbital, so electrons preferentially occupy the 4s orbital first in atoms like calcium and potassium. Electrons fill orbitals based on their energy levels, following the Aufbau principle, which explains why the valence electrons of these elements reside in the 4s orbital.
Will potassium share more properties with calcium or sodium?
Potassium will share more properties with sodium as they both belong to the same group (Group 1) in the periodic table. They both have similar chemical reactivity and form similar types of compounds. Calcium, on the other hand, belongs to Group 2 and exhibits different properties compared to potassium.

Why is calcium more reactive than magnesium?
Calcium is more reactive than magnesium because it is larger than a magnesium atom because it has one more energy level. Valence electrons are on the outermost occupied energy level in the atom and they cause the atom to react, and thus the further the Valence electrons are from the nucleus, the more reactive they are. Therefore, calcium is more reactive than magnesium because the valence electrons on the calcium atom is farther from the nucleus.
How many valence electrons are transferred from the nitrogen atom to potassium in the formation of the compound?
In the formation of the compound, potassium will transfer one electron to nitrogen to achieve a stable electron configuration. Nitrogen needs three additional electrons to reach a stable configuration, so it will receive one electron from potassium, and vice versa, making a total of 2 electrons transferred.
How do you know the chemical reactivities of elements?
The farther the valence electron are from the nucleus, the more easily they can be lost therefore the more reactive the element is. i.e potassium would be more reactive than sodium (check their valence electrons)
