The 2s orbital and 3s orbital both have the same spherical shape and can hold a maximum of two electrons of opposite spin. They only differ because the 3s orbital is further out from the nucleus than the 2s orbital, thus the 3s orbital has a higher energy value.
An electron in a 2s orbital is on average closer to the nucleus.
Two per level (that is, 2 1s, 2 2s, 2 3s, etc.)
the 2s orbital is at a higher energy level
The electrons in the 2p subshell have more energy than those in the 2s subshell, that is energy per electron.See Wikipedia 'Electron Shells' for more on this subject.
All of 11 electrons in sodium are in different electron orbitals: 2 electrons are in 1s orbital, 2 in 2s, 6 in 2p and 1 in the 3s orbital. (This last one is the so-called valence electron)
An electron in a 2s orbital is on average closer to the nucleus.
The number preceding the name of a sublevel ("s") indicates in which electron shell it belongs. Thusly, 2s is the second shell and 3s is the third.
Two per level (that is, 2 1s, 2 2s, 2 3s, etc.)
the 2s orbital is at a higher energy level
There are 9 occupied orbitals in a phosphorus atom's ground state: one 1s orbital, one 2s orbital, three 2p orbitals, one 3s orbital, and three 3p orbitals.
The 2s orbital is larger than the 1s orbital and is higher in energy.
NO
The electrons in the 2p subshell have more energy than those in the 2s subshell, that is energy per electron.See Wikipedia 'Electron Shells' for more on this subject.
The are two electrons in the 3s orbital of magnesium (Mg.)
All of 11 electrons in sodium are in different electron orbitals: 2 electrons are in 1s orbital, 2 in 2s, 6 in 2p and 1 in the 3s orbital. (This last one is the so-called valence electron)
7-2s+4+5s ..... Okay first you combine like terms(add the like terms)..so its going to be 11+3s I did 7+4=11 then -2s+5s=3s So the answer can be 11+3s or 3s+11
Points: (s, 2s) and (3s, 8s) Slope: (8s-2s)/(3s-s) = 6s/2s = 3 Perpendicular slope: -1/3 Midpoint: (s+3s)/2 and (2s+8s)/2 = (2s, 5s) Equation: y-5s = -1/3(x-2s) => 3y-15s = -1(x-2s) => 3y = -x+17x Perpendicular bisector equation in its general form: x+3y-17s = 0
