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 noble gas does oxide ion have the electron configuration for?
Oxide ion (O²⁻) has the electron configuration of a noble gas neon (Ne), which is 1s² 2s² 2p⁶.
What is the electron configuration pattern for calcium?
The electron configuration for calcium is 1s2 2s2 2p6 3s2 3p6 4s2. Calcium has 20 electrons, so it fills the 4s subshell before the 3d subshell to achieve a more stable electron configuration.
What do calcium and oxygen make when they react?
No. Oxygen is an electron receptor (oxidizer) whereas Ca is a doner.
What is the electron configuration using noble-gas notation of calcium?
The electron configuration of calcium using noble gas notation is [Ar] 4s2. This notation indicates that calcium has the same electron configuration as argon ([Ar]) up to the 18th electron, and then adds two electrons to fill the 4s energy level.

Give the electron configuration for calcium the ion?
Neutral calcium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6.
What noble gas does oxide ion have the electron configuration for?
Oxide ion (O²⁻) has the electron configuration of a noble gas neon (Ne), which is 1s² 2s² 2p⁶.
What is the electron configuration pattern for calcium?
The electron configuration for calcium is 1s2 2s2 2p6 3s2 3p6 4s2. Calcium has 20 electrons, so it fills the 4s subshell before the 3d subshell to achieve a more stable electron configuration.
What is the electron configuration of the oxide ion (O2-?
The electron configuration of oxygen in the oxide ion (O2-) is 1s2 2s2 2p6 (equivalent to the configuration of a neon atom), as the oxide ion has gained two extra electrons compared to a neutral oxygen atom.
How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
Draw an electron shell diagram of the ionic compound calicum oxide CaO?
Calcium has 2 valence electrons while oxygen has 6 valence electrons. When adding calcium and oxygen together, they form calcium oxide or CaO, and calciums 2 valence electrons join with oxygens 6 to fill the Lewis structure. Ca 2+ [O with 8e-] 2-
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.
What is the electron dot configuration for calcium?
Calcium has two valence electrons, both of which are unpaired. •Ca•
What figure represents an electron configuration for a calcium atom whose atomic number is 20?
The electron configuration for a calcium atom with atomic number 20 is 1s2 2s2 2p6 3s2 3p6 4s2. This can be represented using the noble gas shorthand notation as [Ar] 4s2, where [Ar] represents the electron configuration of argon.
What do calcium and oxygen make when they react?
No. Oxygen is an electron receptor (oxidizer) whereas Ca is a doner.
What is the electron configuration of calcium in its excited state?
The electron configuration of calcium in its ground state is 1s2 2s2 2p6 3s2 3p6 4s2. In its excited state, one or more electrons transition to higher energy levels. For example, one possible excited state electron configuration for calcium could be 1s2 2s2 2p6 3s2 3p6 4s1 3d1.
