The number of electrons that can be accommodated in an "N" shell is given by the formula 2n^2, where "n" is the principal quantum number of the shell. For example, in the third shell (n=3), the number of electrons that can be accommodated is 2(3)^2 = 18 electrons.
The Bohr model for beryllium is a simplified representation of a beryllium atom where electrons orbit the nucleus in circular orbits at specific energy levels. In this model, beryllium has four electrons arranged in two energy levels or shells, with two electrons in the inner shell and two in the outer shell. The Bohr model helps to explain the electronic structure and properties of beryllium.
In a Bohr model, zinc would have 30 protons and 30 electrons distributed in specific energy levels around the nucleus. The electrons would be arranged in shells or orbits, with the innermost shell containing 2 electrons, the second shell with 8 electrons, and the third shell with 18 electrons.
2 electrons in the K shell and 8 electrons in the L shell
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
The number of electrons that can be accommodated in an "N" shell is given by the formula 2n^2, where "n" is the principal quantum number of the shell. For example, in the third shell (n=3), the number of electrons that can be accommodated is 2(3)^2 = 18 electrons.
The penultimate shell can accommodate a maximum of 8 electrons. This is based on the maximum number of electrons that can occupy each subshell within the penultimate shell (s = 2 electrons, p = 6 electrons).
8 electrons can be accommodated in the 2nd shell (aka 2nd energy level). 2 in the 2s orbital and 6 in the 2p orbitals.
we know that 1st shell contain 2 electrons 2nd shell 8 electrons but third shell have to contains 18 electrons but the maximum no. of electrons that can be accommodated in the outermost orbit is 8 electrons...... by yhell
The first shell in a Bohr model can hold a maximum of 2 electrons.
Valence Electrons: 3d5 4s1in shell model 1
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.

In Bohr's model, electrons in an oxygen atom occupy specific quantized energy levels called shells. Oxygen has two electrons in its innermost shell (K shell) and six electrons in its second shell (L shell). These electrons are arranged in a way that follows the principle of filling the lowest energy levels first before moving to higher ones.

Electronic configurations are the arrangement of electrons in the orbits or shells. The maximum number of electrons that can be accommodated in the shell goes as 2-s, 8-p and so on.. So, when the last shell contains the maximum electrons it can hold, there is no possibility of any reaction to occur because it has the 8 electrons in the final shell already. This arrangement in any atom, which shares or donates or accepts electrons to form the final arrangement as above is called noble gas configuration
1st shell: 2 electrons, 2nd shell: 8 electrons, 3rd shell: 8 electrons, 4th shell: 4 electrons, 5th shell: 0 electrons, 6th shell: 0 electrons.
