Vanadium [ar]3d 3 4s 2: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 shell structure: An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy. A calcium 2+ ion has lost its two valence electrons, and now has 18 electrons. There are 118 elements in the periodic table. Energy level changes as you go up.
Calcium is preceded by argon which has 18 electrons so the remaining two electrons are written after the symbol for argon.
Scandium [ar]3d 1 4s 2: The total electron (19.06042 e) of ca ion are distributed as 17.99558 core electrons, 1.05439 valence electrons and 0.93958 rydberg electrons. A neutral calcium atom also has 20 electrons. Calcium atoms will lose two electrons in order to achieve the noble gas configuration of argon. Mike is correct however let me explain (or try to) unfortunately it is one of those situations where simplifying something really doesn’t help. It looses its two electrons to acquire noble gas configuration.

In order to write the calcium electron configuration we first need to know the number of electrons for the ca atom (there are 20 electrons). View available hint(s) what is the electron configuration of calcium, which has 20 electrons? Or in noble gas form : Atomic mass of calcium is 40.078 u. The condensed electron configuration of calcium and iodine are given below:

Calcium is the 20th element in the periodic table. This means that in a neutral calcium atom, there are 20 protons in its nucleus. The 1s orbital gets 2 electrons, the 2s gets 2, the 2p gets 6, the 3s gets 2, the 3p gets 6, and the 4s gets 2 (2 + 2 + 6 +2 +6 + 2 = 20.) thus, the electron configuration for calcium is: Ca+2 = 1s2, 2s2, 2p6, 3s2,. Look up the electronic configuration of that noble gas and include that value before the rest of the configuration.

Titanium [ar]3d 2 4s 2: This really annoyed me when i got to college as, in schools i was taught this way and then had to learn. The atomic number of calcium is 20. In writing the electron configuration for calcium the first two electrons will go in the 1s. The electron configuration for calcium atom (z = 20 ) is 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 4 s 2 ca atom loses two electrons to form c a 2 + ion the electron configuration for calcium ion is 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6.

Since we need to take away two electrons, we first remove electrons from the outermost shell (n=4). The 1s orbital gets 2 electrons, the 2s gets 2, the 2p gets 6, the 3s gets 2, the 3p gets 6, and the 4s gets 2 (2 + 2 + 6 +2 +6 + 2 = 20.) thus, the electron configuration for calcium is: A neutral calcium atom has 20 electrons, while a calcium atom that has lost two electrons will have 18 electrons, and a neutral argon atom also has 18 electrons. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. Since we need to take away two electrons, we first remove electrons from the outermost shell (n=4).
