which subshell holds the valence electrons of barium?
The subshell that holds the valence electrons of barium is the 6s subshell.
Barium (Ba) is an element with atomic number 56, which means it has 56 electrons. The electronic configuration of barium is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2.
In the electronic configuration, the numbers and letters represent the energy levels (n) and subshells (s, p, d, f), respectively. The superscript represents the number of electrons in each subshell.
The valence electrons of an element are the electrons in the outermost energy level. In the case of barium, the outermost energy level is the 6th energy level (n=6), and the subshell holding the valence electrons is the 6s subshell. In barium, there are 2 valence electrons in the 6s subshell.
It’s important to note that the valence electrons are involved in the chemical reactions and bonding behavior of an element.
