How many of the following elements have 1 unpaired electron in the ground state B Al O F?
In the ground state, only one of the elements listed has 1 unpaired electron: aluminum (Al). Boron (B) has 3 unpaired electrons, oxygen (O) has 2 unpaired electrons, and fluorine (F) has 1 unpaired electron but is already fully paired in its 2p orbital. Therefore, the total count of elements with 1 unpaired electron is two: Al and F.

How many UNPAIRED electrons for the ground-state configuration of Yttrium?
Yttrium has an atomic number of 39, and its ground-state electron configuration is [Kr] 5s². In this configuration, all electrons are paired, resulting in zero unpaired electrons. Therefore, Yttrium has 0 unpaired electrons in its ground-state configuration.
How many unpaired atoms in aluminum?
Aluminum has 13 electrons. Use aufbau principle or periodic table to put these electrons into orbitals. 1s2 2s2 2p6 3s2 3p1 Because there is a lone electron in the p orbital that is not paired, aluminum in its ground state has 1 unpaired electron.
How many unpaired electrons are there in stadium?
Stadium (St) is an element with the atomic number 51. It has a ground-state electron configuration of [Kr] 4d¹⁰ 5s² 5p³. In this configuration, the 5p subshell has three electrons, which are unpaired. Therefore, there are three unpaired electrons in stadium.
Is a phosphorus atom in the ground state paramagnetic or diamagnetic?
Arsenic is paramagnetic because the electron configuration is {Ar}4s^2,3d^10,4p^3. Due to the unpaired electron at the end (4p^*3*) the atom in ground state is paramagnetic. **OR Arsenic would be paramagnetic since the 4 p orbitals each contain one electron with parallel spin. These three unpaired electrons give arsenic its paramagnetic property.
How many unpaired electrons are there in radium?
Radium (Ra) has an atomic number of 88, which means it has 88 electrons. Its electron configuration is [Rn] 7s², indicating that the 7s subshell is fully filled with two electrons, leaving no unpaired electrons. Therefore, radium has zero unpaired electrons in its ground state.
