How many electrons are in the outer shell of the atom of the elements in the second and third rows of the periodic table?

∙ 15y ago
The second and third energy levels of an atom each contain 8 electrons. That is why there are eight elements on the second row (Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, and Neon) and third row (Sodium, Magnesium, Aluminum, Silicon, Potassium, Sulfur, Chlorine, and Argon) of the Periodic Table.

- 2 electrons
- 8 electrons
- 18 electrons
- 32
- (50 electrons, though not proved by discovery of that particular element(s))
- (72)

How many electrons will the elements have in the second group have on the periodic table?
There are 2 valence electrons (electrons in the outer shell) of group 2 elements in the ground (un-ionised or standard) state. This causes them to form +2 ions.
What are the different elements that contain the same number of outer electrons as sodium?
All of the elements in group 1 on the periodic table contain the same number of outer electrons as sodium, which is 1.
What is the most important factor in an elements place in the periodic table?
Its elemental weight
What has 5 electrons in its outer shell?
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
What do elements in the same group in the periodic table have in common?
They have the same number of valence electrons, or electrons in the outer electron shell. This allows them to react with certain elements.

What is common to all elements in the same group in the periodic table?
they have the same number of outer electrons
How do you tell what elements in the periodic table have the same number of electrons in their outer orbitals?
They are in the same column.

What is a colunm in the periodic table?
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
Elements in the second group have 2 outer shell electrons and are also very reactive They are called?
Elements in the second group have 2 outer shell electrons and also very reactive. What are they called?
What is a family on the periodic table?
A family is a column in a periodic table; all elements in a family have similar physical and chemical properties, because they have the same numbers of valence electrons (outer electrons).
What do all group 14 elements have in common periodic table?
All the Group 14 elements has 4 electrons in its outer energy level.
