Answer:
Electronic Configuration of calcium ion: Ca²⁺
1s², 2s², 2p⁶, 3s², 3p⁶
Explanation:
Calcium belong to group IIA and known as alkaline earth metals.
- it have two electrons in outer most orbital.
- these outer two electrons are involve in bonding
- calcium lose these two electron and form cation
- cation have 2+ charge
- calcium have total twenty electrons
Electronic Configuration of calcium atom: ²⁰Ca
1s², 2s², 2p⁶, 3s², 3p⁶, 4s²
When calcium ion is form it loses two electron and have 2+ charge on it.
and have total of 18 electrons
So,
Electronic Configuration of calcium ion: Ca²⁺
the last filled orbital will be 3p⁶
1s², 2s², 2p⁶, 3s², 3p⁶
Rockets, aerial shells, mines, cakes, firecrackers, wheels, fountains (gerbs), lancework, Roman candles and sparklers.
Answer:
s an example, the ground state configuration of the sodium atom is 1s22s22p63s1, as deduced from the Aufbau principle (see below). The first excited state is obtained by promoting a 3s electron to the 3p orbital, to obtain the 1s22s22p63p1 configuration, abbreviated as the 3p level.
