How is the energy level of an elements valence electrons related to its period?

Each period has one more energy level than the last: lets look at group 1 the alkaline metals as an example
H - 1 - one energy level
Li - 2,1 - two energy levels
Na - 2, 8, 1 - three energy levels
K - 2, 8, 8, 1 - four energy levels

∙ 12y agoevery column is a family and they each have the same number of electrons to begin with. but the to become stable, they need to take, or give away electrons to have 8 electrons on there outter shell
Wiki User
∙ 15y agoThey are related because the principal energy level of the valence electron is equal to the period number its located in.
Wiki User
∙ 12y agoits not the energy level that changes but its the number of electrons of protons, the number its assigned to is the amount of electrons or neutrons it has
Wiki User
∙ 12y agoit depends on how close it is to the noble gas
Wiki User
∙ 11y agoThe period number is the same as the highest energy level containing electrons for the atoms in that period.

Which of the elements which have their valence electrons in the second energy level is the largest?
Neon
Why is it significant that valence electrons are located in the outermost energy level of an atom?
The valence electrons are the electrons that undergo chemical bonding in the main group or representative elements.
The ability of atoms to combine with other atoms is determined by?
The number of electrons of both atoms and its valence number.
How does the energy of the core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
How does the energy of core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
Which of the elements which have their valence electrons in the second energy level is the largest?
Neon
Why is it significant that valence electrons are located in the outermost energy level of an atom?
The valence electrons are the electrons that undergo chemical bonding in the main group or representative elements.
How are families within the periodic table similar?
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.
Outermost principal energy level?
That, or they, would be the outer most shell electrons. The one(s) that get shared when elements bond. The one that moves out and up when struck by a photon. The one that makes light when it falls back down (gives up its' energy) to its' original shell. ADD: It is a valence electron.
How can period number related to the location of valence electrons?
The period number is the same as the energy level containing the valence electrons. For example, in period 4, the valence electrons are the 4s and 4p electrons.
How many valence electrons do the boron group have?
Boron is located in group 3A. It is group 13 in modern notation. This set of elements have three valence electrons.Boron is in the 13th group in the periodic table. Elements in this group has 3 electrons in the outermost energy level. That means they have 3 valence electrons.
The ability of atoms to combine with other atoms is determined by?
The number of electrons of both atoms and its valence number.
How many electrons are in the highest occupied energy level of oxygen?
Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons. All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.
How does the energy of the core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
How does the energy of core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
How many electrons does an atom need to a outer energy level?
There are different numbers of valence electrons in different elements.
