Want this question answered?
The energy levels and orbitals the electrons are in
valence electrons
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.
Sort of but not exactly.A neutral isolated atom of boron has, nominally, three occupied electronic energy levels (1s, 2s, and 2p).However, it has an infinite number of unoccupied energy levels (as do all atoms).Also, in compounds, there's a strong tendency for the 2s and 2p orbitals to "hybridize", forming sp, sp2, or sp3 orbitals, each of which has its own characteristic energy level.Boron does not have three energy levels. If you know the element's principle quantum number, then you can find how many electrons can fit in an atom of a specific element. In this case, Boron can only store 2p1/2 (p is the principle quantum number) electrons. This is getting too complex, and isn't required for you to know as of this exact moment. The answer is that Boron only has two energy levels.
The arrangement of electrons in an atom.
The period that the element's in is the same number of how many valence electrons (energy level of outer electrons) there are in the element...
8 electrons.
Yes. They are found in different energy levels. The number of energy levels depends on the element under consideration.
The atom of an element in the third period of the Periodic Table has 3 energy levels and so on. Also, atoms of elements in the same group have the same no. of valence electrons.
bromine, i think
that depends on the number of electrons the more electrons the more energy
10
bromine, i think
Symbol, Name, Atomic Number, Atomic Mas, Energy Levels, Electrons
the period number tells which is the highest energy level occupied by the electrons
The energy levels and orbitals the electrons are in
If it has electrons in three different energy levels, then it must be in period 3 of the periodic table. To have the fewest electrons, it would be in group 1. So, the element in group 1, period 3 is sodium (Na).
