Gold has 25 valence electrons
Type your answer here... The number of valence electrons in calcium is 20, because it's almost the same thing as it's atomic number.
its in column two on the periodic table, so therefor it has two valence electrons .
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.

Calcium has two valence electrons.
Calcium has two valence electrons.
There are only 2 valence electron found in calcium.
There are 2 electrons in valence shell of calcium. :-)
Calcium is a non metal element. There are 20 electrons in a single atom.
Calcium has 2 valence electrons, like all Group 2 elements.
Calcium has 2 valence electrons and it typically loses these 2 electrons to achieve a stable configuration.

Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.
