What is the expanded electron configuration for es?
Einsteinium has the atomic number of 99. Thus, it has 99 protons and, to keep it neutral, 99 electrons. Filling in the first 99 electron orbitals gives us the electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f11.
How many electrons are in the nucleus of einsteinium?
Einsteinium has 99 protons and 99 electrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element Einsteinium's atomic number is 99 but Es has 19 known isotopes.
What is your ideal weight you are 5f11?
For someone with the height of 5'11, their ideal weight should be between 130-170 pounds. This is based on the BMI chart.
15 and 5f11 126 pounds would it be good for your 100m time if you were heavier?
I don't know if gaining any weight would help your time, but if your that skinny it probably isn't too healthy, I'm a couple inches taller than you but I'm seventy pounds heavier and my 100 meter time is fine.
