Zero. Calcium has two electrons in its 4s sublevel, and none in the 3d sublevel. The 3d sublevel doesn't start filling until after the 4s sublevel is filled.
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.

Sodium and calcium each have the same number of orbitals. These two elements (in their neutral, ground state) have 6 electron orbitals: 1s, 2s, 2px, 2py, 2pz, 3s.
Two orbitals.
There are 27 electron containing orbitals in an atom of Iodine.
2 p orbitals
Calcium. You can check other orbitals for other elements using ptable.com and clicking on the tab at the top labeled "orbitals". It gives you electron configurations for all elements.

Technetium has five electron shells.
If it is in row 4 (4th period) it has 4 energy levels occupies. In the 2nd column (group 2A) it has 2 valence electrons. You ask how many orbitals it has. It has s and p orbitals. Is that what you mean? The configuration is 1s2 2s2 2p6 3s2 3p6 4s2 so there are 3 s orbitals and 6 p orbitals for a total of 9 orbitals.

You don't. Calcium is not an electron, calcium is a element
Orbitals. Not to be confused with orbits. They don't actually move in 'paths' either. Due to their nature, you cannot determine the exact location of an electron and still know where it will be next. (See "Heisenberg Uncertainty Principle") Orbitals actually are mathematical functions which describe the probability of finding an electron in a given space.
