Since the d orbital can hold 10 electrons, half filled would mean it has 5 electrons. The element in period 6 that has 5 electrons in the d orbital would be Rhenium (Re).
The element in Period 4 that has two electrons in the p sublevel is germanium (Ge). It has the atomic number 32 and is located in group 14 of the periodic table. In its electron configuration, germanium has the outermost electrons in the 4s and 4p sublevels, with the 4p sublevel containing two electrons.

Chromium (Cr) is a period 4 transition element that can form a 2+ ion with a half-filled d sublevel. In its 2+ ion state, chromium has a d5 configuration, with the 3d orbital half-filled.
The d suborbitals begin at period 4, but the d-sublevel is actually 3d. The first element is scandium, which has the atomic number of 21.
The element is francium.
The element with its outermost electrons in an S sublevel is found in Group 1 and Group 2 of the periodic table. These elements have their outermost electrons in the S sublevel before transitioning to the D sublevel in subsequent groups.
The element in Period 4 that has two electrons in the p sublevel is germanium (Ge). It has the atomic number 32 and is located in group 14 of the periodic table. In its electron configuration, germanium has the outermost electrons in the 4s and 4p sublevels, with the 4p sublevel containing two electrons.
Calcium is the element that has 2 electrons in the 4s sublevel.
The element that completes the 7s sublevel is radium, with the electron configuration 7s2.
If you tell me what an f block element is i can help you out. I aced chemistry last semester and ill probably be tutoring it next semester. are u referring to the families in the periodic table?
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.
The 2p sublevel is completed with six electrons and is found in elements from carbon (C) onwards. The seventh element, nitrogen (N), is the element that completes the 2p sublevel.

Ca
Phosphorus has 3 electrons in the 4p sublevel.
The 3p sublevel is completed by the noble gas element Argon (Ar) which has 18 electrons in total.
