Calcium has to lose 2 electrons to form noble gas configuration.
Calcium has 2 valence electrons and it typically loses these 2 electrons to achieve a stable configuration.
Calcium will lose two electrons to gain the noble gas configuration of Argon.
Calcium should lose 2 valence electrons and attain the noble gas configuration of argon with 18 elements.
The electronic configuration of calcium in calcium hydroxide is the configuration of a calcium +2 ion, which is the same as the configuration of the preceding noble gas, argon.
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
Calcium has 2 valence electrons and it typically loses these 2 electrons to achieve a stable configuration.
2 electrons as it has 2 valence electrons, hence it has a tendency to lose 2 electrons to achieve noble gas configuration
Calcium will lose two electrons to gain the noble gas configuration of Argon.
Calcium should lose 2 valence electrons and attain the noble gas configuration of argon with 18 elements.
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
Calcium has 20 protons and 20 electrons. When we fill in the first 20 orbitals, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2. Since 4 is the outermost shell in this configuration, calcium has 2 valence electrons.
calcium has the complete electronic configuration: 2, 8, 8 2 and hence has 2 valence electrons.
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
Calcium has two valence electrons, both of which are unpaired. •Ca•
The electronic configuration of calcium is 2, 8, 8, 2 and the fourth energy level has 2 electrons.
Calcium atoms have two electrons in the s orbital of their outermost energy level. Their electron configuration is [Ar]4s2.
