Each orbital contains at maximum 2 electrons.
there is one s-orbital: 2 in this alone
there are three p-orbitals (px, py, pz) with 2 in each
there are five d-orbitals (dz2, dxz, dyz, dxy dx2-y2) with 2 in each
there are seven f-orbitals (fz3, fxz2, fyz2 ,fxyz ,fz(x2-y2) ,fx(x2-3y2) ,fy(3x2-y2) with 2 in each
what term describes elements that contain the same number of valence electrons
1st orbit - 2 2nd orbit - 8 3rd orbit - 8 all together all three orbits can hold up to 18 electrons.
A sodium atom has an atomic number of 11, meaning it has 11 electrons. The first orbit, or energy level, can hold a maximum of 2 electrons. Therefore, in a sodium atom, the first orbit contains 2 electrons.
Aluminum has three electrons in its outermost shell (valence electrons). Elements in the same group of the periodic table as aluminum, such as gallium (Ga) and indium (In), also have three valence electrons. Therefore, both gallium and indium share the same number of electrons in their outermost orbit as aluminum.
It depends on the atomic number. For example, to find the number of electrons in carbon, look at a periodic table. You will see that the atomic number for carbon is 6, so 6 electrons orbit a carbon atom'snucleus.

Two (2) electrons can be held in the first orbit.
The number of electrons per orbit in an atom is determined by the energy level of the orbit. Each orbit can hold a maximum number of electrons, with the first orbit holding up to 2 electrons, the second holding up to 8 electrons, the third holding up to 18 electrons, and so on.
In a lead atom, the number of electrons in each orbit are as follows: 2 electrons in the first orbit (closest to the nucleus) 8 electrons in the second orbit 18 electrons in the third orbit 32 electrons in the fourth orbit
95 electrons, two of them are in the outer orbit.
2 electrons maximum. 1s2
The maximum number of electrons that can be held in the third orbit of an atom is 18. This is based on the formula 2n^2, where n is the principal quantum number of the orbit. For the third orbit (n=3), the maximum number of electrons is 2 x 3^2 = 18.
2 electrons is the maximum number for an single orbital.
No, they contain different number of electrons. Isotopes differ in their number of neutrons.
The number of protons is usually the same as the number of electrons!:)
