WebThe s subshell has 1 orbital that can hold up to 2 electrons, the p subshell has 3 orbitals that can hold up to 6 electrons, the d subshell has 5 orbitals that hold up to 10 electrons, and … Web2 days ago · Q: A block of mass m₁ = 14.0 kg is connected to a block of mass m₂ = 32.0 kg by a massless string that… A: Given: m1 = 14kg m2 = 32kg k = 300 N/m h = 18 cm Apply the energy conservation equation. The p orbital can hold a maximum of six electrons, hence there are six columns in the p-block. Elements in column 13, the first column of the p-block, have one p-orbital electron. Elements in column 14, the second column of the p-block, have two p-orbital electrons.
