The orbital diagram of selenium shows that the 1s subshell has 2 electrons, the 2s subshell has 2 electrons, the 2p subshell has 6 electrons, the 3s subshell has 2 electrons, the 3p subshell has 6 electrons, the 4s subshell has 2 electrons, the 3d subshell has 10 electrons, and the 4p subshell has 4 electrons. The electron holding capacity of each orbit is 2n2. What is the maximum total number of electrons possible in the 2p subshell? As a result, if two electrons have the same principle, azimuthal, and magnetic numbers, they must have opposite spins. The d subshell has 5 orbitals and thus can accommodate a maximum of 10 electrons. Thus n=1 shell can hold two electrons. Now, the #4p# subshell contains a total of three #4p# orbitals, #4p_x#, #4p_y#, and #4p_z#. Describe the structure and function of each type of epithelial tissue. The atomic number of selenium represents the total number of electrons of selenium. So in this case, the valency of selenium is 2. Electrons can either jump to a higher energy level by absorbing, or gaining energy, or drop to a lower energy level by emitting, or losing energy. The 4s orbital is now full. The remaining six electrons will be allocated to the 2p orbital. The following table lists all of the possible subshells for n values up to 4: As a result, the 1p, 2d, and 3f orbitals do not exist because the value of the azimuthal quantum number is always less than the value of the principal quantum number. Best Answer Copy The formula for how many electrons are in a given shell is: 2n2 where n= # of shells. The number of atomic orbitals in a d subshell is. To write the orbital diagram of selenium(Se), you have to do the electron configuration of selenium. Explanation: A 4p orbital, which is part of the p subshell located on the fourth energy level, can hold a maximum of two electrons. Because the 1s orbital can only hold two electrons, the next two electrons for Ne are placed in the 2s orbital. The colors of the visible spectrum are red, orange, yellow, green, blue, and violet. Your email address will not be published. Ans. The energy of an orbital is calculated by adding the principal and azimuthal quantum numbers.
