What element's neutral atoms have 20 protons?
it is about the atomic number. Calcium is the element.
Why does not calcium has 10 electron in its 3rd shell?
Because then it would be zinc!Calcium has the electron configuration [Ar] 4s2Zinc has the electron configuration [Ar] 3d10 4s2
What is the electron configuration?
The arrangement of the electrons in an atom is known as its electron configuration.
What is the complete ground state electron configuration for the gallium atom?
The electron configuration of gallium is: [Ar]3d104s24p1.
What is the electron configuration pattern for calcium?
fuuucck youuu .
What figure represents an electron configuration for a calcium atom whose atomic number is 20?
The electron configuration of calcium is [Ar]4s2.
How many electrons are there in the neutral atom which has the ground state outer electron configuration of 4s2?
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
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 the NOBLE GAS notation write the electron configuration for the calcium atom?
[Ar] 4s2
What is the electron configuration of calcium in its excited state?
The electron configuration of calcium is [Ar]4s2.
What is the electron configuration of a calcium atom whose atomic number is 20?

The full electron configuration for sulfur atom?
The full electron configuration for sulfur atom is 1s2.2s2.2p6.3s2.3p4.
What element's neutral atoms have 20 protons?
it is about the atomic number. Calcium is the element.
The element fluorine has 9 electrons which is the electron configuration for an atom of fluorine?
The electron configuration for an atom of fluorine is [He]2s2.2p5.
About the electron configuration?
Electron configuration for an atom is the distribution of electrons on atomic orbitals.
When a calcium atom loses its valence electrons the ion formed has an electron configuration that is the same as an atom of?
Argon. Calcium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2, and when it loses its valence electrons (the outermost 4s2 electrons) it has a configuration identical to argon. If you don't know about sublevels, then disregard that. Calcium has a configuration of 2-8-8-2, and when it loses its 2 valence electrons, it has a configuration identical to argon in the ground state. Hope that cleared it up
