0 beryllium is a organic Chinese herb that originated in a pertrolium river on the planet mars
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
2 energy levels
Two
5

bismuth has six energy levels
Principal energy levels are an atom's major energy levels, ranging in value from 1 to 7. Energy sublevels are contained within principal energy levels, and their number increases as the value of the principal energy level increases.
Down a group, the number of energy levels (or shells) increases.
The period number tell about the energy levels occupied by electrons
The Group Number
bismuth has six energy levels
The number of energy levels is equal to the period number of the element. Through a group, the number of energy levels increases. All the elements in a period has the same number of energy levels.
Principal energy levels are an atom's major energy levels, ranging in value from 1 to 7. Energy sublevels are contained within principal energy levels, and their number increases as the value of the principal energy level increases.
no
The quantum number relating to the size and energy of an orbital
The period number is equal to the number of energy levels. Elements of period 3 have 3 energy levels. Na,Mg,Al,Si are few elements in the period 3.
Yes. They are found in different energy levels. The number of energy levels depends on the element under consideration.
Down a group, the number of energy levels (or shells) increases.
The period number tell about the energy levels occupied by electrons

i just cant find it
valence electrons
