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!
You can determine the number of electrons in an element's orbital shells by looking at its atomic number, which tells you the number of protons and electrons in a neutral atom. The electron configuration of an element provides a more detailed breakdown of how the electrons are distributed among the different orbital shells.
There are two electrons in the 3p orbital of Silicon. Each p orbital can hold a maximum of 2 electrons.
Platinum is in the 6th period, meaning its atom has 6 energy shells. It is in Group 10 and has 78 electrons.
The beryllium atom has 2 electron shells. The first shell, closest to the nucleus, can hold up to 2 electrons, while the second shell can hold up to 8 electrons. Beryllium has 4 electrons, filling both of its electron shells.
Cadmium (Cd) has 48 electrons in total. It has configurations of 2, 8, 18, 18 and 2 electrons in its electron shells. This means that cadmium has 2 electrons in its 5s orbital.
An element in period 3 and group 16 of the periodic table has 3 electron shells. It also has 6 valence electrons since group 16 elements have 6 electrons in their outermost shell.
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.
Two electrons in the outer shell of radium.
Oxygen has 2 electrons in the innermost orbital and 6 in the outermost (valence) orbital.
Francium has seven electron shells; electrons per shell: 2, 8, 18, 32, 18, 8, 1.
Oxygen is a non metal element. There are 8 electrons in a single atom.
Mercury has 80 electrons which means there are 6 shells in a neutral atom of mercury.
Boron has two orbital shells. The first shell contains 2 electrons, while the second shell can hold up to 8 electrons. Boron typically has 5 electrons, with 2 in the first shell and 3 in the second shell.
There are two electrons in the 3p orbital of Silicon. Each p orbital can hold a maximum of 2 electrons.
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.
The spacecraft entered the Earth's orbital path, allowing it to circle the planet continuously.
Radon is a non metal element. There are 86 electrons in a single atom.
