The outer shell of calcium has two electrons.
There are 2 electrons on the outermost shell of calcium.
Calcium has two electrons in the outer shell.
There are 2 electrons in valence shell of calcium. :-)
Helium (He) and Calcium (Ca) both have 2 valence electrons.
Sulfur has six electrons in its third electron shell.
The third shell can hold a maximum of 18 electrons.
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
It's over 9000!
The third shell of an atom can hold a maximum of 18 electrons. The first shell can hold up to 2 electrons, the second shell up to 8 electrons, and the third shell up to 18 electrons based on the formula 2n^2, where n is the shell number.
The third electron shell can hold a maximum of 18 electrons.
the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
