What else can I help you with?
What is the electronic configuration of calcium in calcium hydroxide?
The electronic configuration of calcium is 1s2 2s2 2p6 3s2 3p6 4s2. In calcium hydroxide (Ca(OH)2), calcium loses its two outer electrons to form Ca2+ ion, which has the electronic configuration 1s2 2s2 2p6 3s2 3p6.
The element that forms a 2 plus ion with the same electronic configuration as Ar?
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
Is the electronic configuration of calcium 2882 or 2891?
The electronic configuration of calcium is 2882. This means that it has 20 electrons in total, with 2 electrons in the 1s orbital, 8 electrons in the 2s orbital, 8 electrons in the 2p orbital, and 2 electrons in the 3s orbital.
How many shells do calcium have?
Calcium has 20 electrons in its electronic configuration, therefore it has 20 shells.
What is the electronic configuration for calcium chloride?
CaCl2 . electronic configuration of ca2+ 1s2 2s2 2p6 3s2 3p6. electronic configuration of Cl1- 1s2 2s2 2p6 hope this helped!
What is the valence electron configuration for calcium atom?
calcium has the complete electronic configuration: 2, 8, 8 2 and hence has 2 valence electrons.
What is electronic configuration of 40CA?
The electronic configuration of Calcium (Ca) is 1s2 2s2 2p6 3s2 3p6 4s2.
A calcium ion has the same electron configuration as what other element?
Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.
Does k2plus and ca have the same electronic configuration as argon?
No, potassium (K) in its K2+ cation form and calcium (Ca) have different electronic configurations than argon (Ar). Potassium has an electron configuration of [Ar] 4s1 and calcium has an electron configuration of [Ar] 4s2. In contrast, argon has an electron configuration of 1s2 2s2 2p6 3s2 3p6.
What element is ar3d34s2?
[Ar]3d34s2 is the shorthand electron configuration for Vanadium (V).
How many electrons are in the outer energy level for calcium?
There are 2 electrons in the outer energy level for calcium, as it is located in the 4th (outermost) energy level of the electronic configuration.
Why the configration of calcium is 2882 not 2810?
since the number of electrons for calcium atom is 20 so the elctronic configuration of Ca will be like the following: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 so, 2882 is the electronic configuration of calcium and not 2810.
