The number of orbitals is easy. Find out the number of electrons (atomic number) and then separate it into the relevant shells. GCSE: you are required only to know the electron configuration e.g. 2.8.8.... A-Level: sort it into sub-levels 1s, 2s, 2p, 3s, 3p, 4s, 3d.... Ok, so if you are taking the element Mg into consideration GCSE: 2.8.2 A-Level: 3 row down (so 3rd sub-shell) and the s-block of the Periodic Table 1s2, 2s2, 2p6, 3s2 Finito!
Two energy shells. Made up as 1s2, 2s2 Shells 1 & 2 each have only 's' orbital and each orbital has only two electrons in it. The outer shell '2' is more energetic. The electrons are paired and spin in opposite directions to each other.
Platinum is in the 6th period, meaning its atom has 6 energy shells. It is in Group 10 and has 78 electrons.
There are two electrons in the first shell of neon. Its complete electronic configuration is 2,8
Yes a single orbital in the 3d level can hold 2 electrons.
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
there are two shells of electrons in the nitrogen atom that actually have electrons in them, nitrogen has two electrons in the first shell, the S orbital, and five in the outer shell, the P orbital. this causes nitrogen to have a valence shell with five electrons.
Orbital Notation is a way to show how many electrons are in an orbital for a given element.
Oxygen has 2 electrons in the innermost orbital and 6 in the outermost (valence) orbital.
Two electrons in the outer shell of radium.
There are 80 electrons shells for mercury.
By determining the element's orbital diagram, or its electron configuration.
Boron has 2 shells altogether. 2 electrons on the first one and the remaining three on the second. Altogether boron (B) has 5 electrons.
Oxygen is a non metal element. There are 8 electrons in a single atom.
Two energy shells. Made up as 1s2, 2s2 Shells 1 & 2 each have only 's' orbital and each orbital has only two electrons in it. The outer shell '2' is more energetic. The electrons are paired and spin in opposite directions to each other.
The outer shell (N=4) of the copper element has 2 electrons.
Platinum is in the 6th period, meaning its atom has 6 energy shells. It is in Group 10 and has 78 electrons.
Francium has seven electron shells; electrons per shell: 2, 8, 18, 32, 18, 8, 1.
