Loss or gain of electron for calcium?
Calcium usually loses 2 electrons, giving a cation of Ca2+
To form an ion what does a calcium atom gain or loose?
An atom of Calcium will lose an electron to become a posotive ion.
Does calcium give away elctron and gain electron?
No, it can not do both at the same time.
How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
How do you know calcium is an electron?
You don't. Calcium is not an electron, calcium is a element
What is the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
two electron should be lost
How do lithium and fluorine become stable together?
lithium donates the electron in its outer orbital to fluorine which then has a completed outer shell
What is the electron configuration of calcium in its excited state?
The electron configuration of calcium is [Ar]4s2.
What happens if a calcium atom loses an electron to a chlorine atom?
Because calcium has 2 valence electrons, it needs to get rid of them to have a stable noble gas conformation. Chlorine atom has 7 VE and only needs to gain one electron to have the noble gas conformation. Therefore one calcium will give one electron to two chlorine atoms, therefore resulting in an ionic bond.
What is the difference between electron affinity and electron gain enthalpy?
electron affinity is the negative of electron gain enthalpy. for example, the electron gain enthalpy of fluorine is -328, and electron affinity is 328 which is -(-328)
What is the Configuration for calcium.?
The electron configuration of calcium is [Ar]4s2.
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
