What happens to the number of electrons in the outer energy level as you go down the periodic table?

The number of shells increases. Moving down the periodic table leads an investigator to heavier elements, that is, elements with bigger atomic numbers. That means larger nuclei and more electrons, which will have to make themselves homes out in the electron cloud. More shells will be set up to provide places for those electrons to hang out.

The number of electrons in the outer energy level generally increases as you go down the Periodic Table. This is because each row adds a new energy level, allowing for more electrons to occupy the outermost shell of an atom.

Does the number of each period in the modern periodic table represents the number of?
Yes, the number of each period in the modern periodic table represents the number of electron shells (energy levels) that an atom's electrons occupy. Each period corresponds to a new energy level being filled by the electrons in the atoms of the elements in that period.
When moving down a group in the periodic table what does the number of valence electrons do?
The number of valence electrons increases by one as you move down a group in the periodic table. Valence electrons are the electrons in the outermost energy level of an atom, and they determine the chemical properties of an element.
What do you notice about the energy levels in an atom of an element and the period the element is in?
the period number tells which is the highest energy level occupied by the electrons
What does the period number tell about the energy levels ocupied by electrons in an atom?
The period number tell about the energy levels occupied by electrons
What happens to the energy levels are you move from left to right on the periodic table?
As you move from left to right across the periodic table, the energy levels of the electrons remain the same but the number of electrons in the outer shell increases. This results in elements on the right side having higher effective nuclear charge, making it harder for electrons to be removed and causing a general increase in electronegativity and ionization energy.
What shows the number of electrons in the outer energy level?
The group number on the periodic table shows the number of electrons in an element's outer energy level. Elements in the same group will have the same number of electrons in their outermost energy level.
How is the number of energy levels in an atom related to the periodic number?
The period number is the same as the highest energy level containing electrons for the atoms in that period.
What does the period number tell you?
The period number in the periodic table indicates the energy levels or shells where the element's electrons are located. Elements in the same period have the same number of electron shells.
Does the number of each period in the modern periodic table represents the number of?
Yes, the number of each period in the modern periodic table represents the number of electron shells (energy levels) that an atom's electrons occupy. Each period corresponds to a new energy level being filled by the electrons in the atoms of the elements in that period.

What are electrons on a periodic table?
Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons
Period in chemistry?
A period is a horizontal row on the periodic table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.
What does the period number tell about the energy levels ocupied by electrons in an atom?
The period number tell about the energy levels occupied by electrons
What energy state do electrons automatically fill?
As the periodic table of the elements is built up by adding the necessary electrons to match the atomic number, the electrons will take the lowest energy consistent with the Pauli exclusion principle.
Which group in the periodic table has a stable number of electrons in their outer energy levels?
noble gases or group 1
What happens as periods increase on the periodic table?
As you move across a period on the periodic table, the number of protons increases, which increases the atomic number. This results in a greater positive charge in the nucleus, leading to an increase in the attraction between the nucleus and the electrons in the outer energy levels. This trend generally results in smaller atomic size and higher electronegativity as you move across a period.
