The largest atom is calcium which has 4 shells.
Calcium has 20 electrons in its electronic configuration, therefore it has 20 shells.
A neutral atom of calcium has 20 electrons arranged in the electron shells. The electron configuration for calcium is 2-8-8-2. The first two shells (K and L) are completely filled, while the M shell is partially filled with 2 electrons.
A sulfur atom has 3 electron shells.
A sodium atom has 3 energy shells.
A bismuth atom has 6 electron shells.
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
Yes, clam shells contain calcium carbonate which is a form of calcium. Calcium is a key component of shell formation in many marine organisms, including clams.
A neutral atom of calcium has 20 electrons. Electrons fill the electron shells in order of increasing energy levels, with the first shell holding a maximum of 2 electrons, the second shell holding a maximum of 8 electrons, the third shell holding a maximum of 18 electrons, and the fourth shell holding the remaining 2 electrons. Thus, three electron shells (the first three shells) would be completely filled by a neutral atom of calcium.
There are 20 electrons in a calcium atom.
shells have a many uses like, gardening, good source of calcium, and as a ferteliser
