The number of orbitals that are completely full is 5.
The reason you may have thought it was 3 is because you're confusing orbitals with subshells.
In this electron configuration, the sub shells are: 1s^2, 2s^2, 2p^6, 3s^1
So, we have four sub shells.
Each sub shell consists of a specific number of orbitals. s subshells have one orbital, p subshells have three orbitals, d subshells have five orbitals, and f subshells have seven orbitals. Knowing this, we can look back at the electron configuration we were given and determine how many orbitals are filled.
1s^2 has one orbital, 2s^2 has one orbital, 2p^6 has three orbitals, and 3s^1 has one orbital. The first three subshells are completely full, so a total of five orbitals are full.
I think the correct answer from the choices listed above is the first option. The condition that can determine whether a system is in equilibrium is when deltaG is equal to zero. Hope this answers the question. Have a nice day. Feel free to ask more questions.
Answer:
Buckminsterfullerence is called an allotrope of carbon because it was discovered during an experiment involving a cluster of beam which uses laser to vapourise a graphite rod in a helium atmosphere to produce carbon plasmas.a mass sectrometry evidence from the experiment showed that carbon molecules with C60 were forming with a spheroidal geometry.so therefore it was included as an allotrope of carbon.
Answer:
It's a Lithium atom
Explanation:
You can count the red particles in the nucleus, they're the protons. This atom have 3 protons. The atom that have 3 protons is the Lithium atom
