In the molecule ClF5, chlorine makes five covalent bonds. Therefore, five of its seven valence electrons need to be unpaired. The orbitals with the same energy are known as degenerate orbitals. For example, the p subshell has three degenerate orbital, namely, px, py, and pz. How many degenerate orbitals are needed to contain seven electrons with five of them unpaired

6 orbitals

Explanation:

Each orbital holds 2 electrons so for 5 of 7 orbitals to have unpaired electrons, five orbitals will have one electron and one orbital will have two electrons making 7 total electrons and 6 total orbitals.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
