The element Calcium (Ca) has 20 electrons according to its atomic number which is 20.
Calcium is a meta element. Atomic number of it is 16.
No; That is the atomic weight of Calcium.
If an atom loses electron, then it will have a positive oxidation number. If an atom gains electron, then it will have a negative oxidation number.
The electron configuration of iron, atomic number 26, is [Ar]3d64s2. The expanded electron configuration is 1s22s22p63s23p63d64s2.

If an atom loses electron, then it will have a positive oxidation number. If an atom gains electron, then it will have a negative oxidation number.
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.

group number
Electron dot formula tells the number of valence electrons
The mass number of an electron is 5.485 799 095 x 10-4 amu.
Yes, it can. When the element loses electron, the oxidation number increases and when it gains electron, the oxidation number decreases.
subtract the number of protons from the number of electrons. The above answer does not answer the question!!
