In the nucleus. The nucleus is where the protons and the neutrons of the atoms are. Electrons are only have around 1/2000 of a proton's mass, so it is usually ignored
I think it is 3, but I'm not sure
Answer:
79.904 grams.
Explanation:
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Bromine, or 79.904 grams.
Based on the data given, the energy required to remove an electron from a hydrogen atom in the n = 11 state is -0.112 eV
<h3>What is ionization energy?</h3>
Ionization energy is the energy requiredto remove an electron from a neutral atom or a cation in its gaseous state.
To calculate the energy required to remove the electron from a hydrogen atom in the n = 11 state, the formula below is used:
where

substituting the values:

Therefore, the energy required to remove an electron from a hydrogen atom in the n = 11 state is -0.112 eV
