Since the electron arrangement is 2,8,18, and 32, the electron arrangement for a calcium atom is 2,8, and 10.
This chemical element is calcium (Ca).
Phosphorus
Calcium has two valence electrons, so it would have two electron dots in a Lewis electron dot diagram.
Na+ and neon are isoelectronic.
4 electron shells; 2 electrons in first, 8 in second, 8 in third and 2 in valence shell.
it is 2,8,8
This chemical element is calcium (Ca).
You don't. Calcium is not an electron, calcium is a element
No, calcium (Ca) has a unique electron configuration due to its atomic number and position in the periodic table. Its electron arrangement is 1s2 2s2 2p6 3s2 3p6 4s2. While there are other elements with similar electron configurations, none are identical to calcium.
Phosphorus
Chlorine needs to gain one electron to achieve the same electron arrangement as neon, which has a stable octet (eight valence electrons). By gaining one electron, chlorine will have a full outer shell with eight electrons, resembling the electron arrangement of neon.
your cute
2,4.
three dimensional arrangement of atoms electron-group geometry
The electron configuration of plutonium is: [Rn]5f67s2.
Calcium has two valence electrons, so it would have two electron dots in a Lewis electron dot diagram.
All of the elements in Period 3, excluding group 18/VIIIA, have the same inside electron arrangement as phosphorus. They all have the electron configuration of neon as their inside arrangement of electrons.
