What does the number at the top of each column in the periodic table mean?
The number at the top of each column in the periodic table is the group number. It indicates the number of valence electrons an element in that column has, which influences its chemical properties. Elements in the same group tend to have similar chemical behavior due to their shared number of valence electrons.
What does the number on top of the symbol mean in the periodic table?
It is the Atomic Number.
What do you mean by group in periodic table?
The columns in the periodic table are groups, also called families because the elements in a group have similar properties.
What does additional contact telephone mean?

What does FN mean on the periodc table and What is it's number?
There is no Fn on the periodic table of elements. However, there is Fm, Fermium, number 100.
Why are elements grouped in the periodic table?
I am assuming you mean to ask why elements go into specific groups Elements that have the same number of valence electrons are put into the same group. Because they all have the same number of valence electrons, it could also be said that elements are put into groups based on their chemical properties.
What does Th mean in the periodic table?
Th is element number 90 on the periodic table It is thorium, it is in the Actinides, and it is radioactive

Groups are made of these columns that go up and down?
Groups in the periodic table are made of columns that go up and down and are called groups or families. Each group/family has elements that share similar chemical properties because they have the same number of electrons in their outermost energy level.
What does it mean to be in the same group?
In the periodic table, elements in the same group, or family, have similar properties. This is because the number of valence electrons is consistent within groups. For example, the Noble Gases all have 8 valence electrons.
What is the operation you can use to find how many in all when you combine equal groups?
If, by "equal groups", you mean groups of equal things, you get how many in all [the total number] by simply addingthem all together. Sometimes adding is called summation.If, by "equal groups", you mean equal-sized groups of things, you get how many in all by multiplying the number of groups by the number of things in each member group.The number of things in a group is also called its cardinality. Loosely, cardinality is the size of the group, or the number of elements ["things"] in the group.
