the orbital is in the energy level closest to the nucleus.
95% of the time (or any other percentage you choose), the electron will be found within a fairly easily defined region of space quite close to the nucleus.
Heisenberg Uncertainty Principle says - loosely - that you can't know with certainty both where an electron is and where it's going next
1s orbital. The "1" represents the fact that
shape of the orbital
s orbitals are spherically symmetric around the nucleus
similar to a 1s orbital
this is an orbital at the second energy level.
further from the nucleus
another region of slightly higher electron density
nearer the nucleus.
Electron density" is another way of talking about how likely you are to find an electron at a particular place.
2s (and 3s, 4s, etc) electrons spend some of their time closer to the nucleus
effect of this is to slightly reduce the energy of electrons in s orbitals
nearer the nucleus the electrons get, the lower their energy.
Not all electrons inhabit s orbitals
few electrons live in s orbitals
At the first energy level, the only orbital available to electrons is the 1s orbital
