Groups are the vertical columns on the table and they represent how many valence electrons the elements in th group have. There are 8 groups, from Hydrogen to Helium (metals aren't included because they can have a various number of valence electrons; they are identified in a different way, in the B category). The groups are A1, A2, A3, A4, A5, A6, A7, and A8. Simply, elements in group
A1 have 1 valence elctron, group A2 have two, so on..
The Periodic Table tells you how many protons are in an atom by their Elemental Number. In other words, yes, the Periodic Table tells you how many protons are in an atom.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
No, the symbol "H" stands for Hydrogen on the periodic table. The symbol "He" stands for Helium on the periodic table.
The abbreviation for potassium is " K " in the periodic table. It is placed in group-1 of the periodic table.
These names are the names of chemical elements.
The periodic table is in order of atomic mass
The periodic table tells you chemical elements. :)
They run from left to right

How many valence (outer shell) electrons an element has.
the benefit is that you can tell the atomic number atomic mass its symbol and where it is on the periodic table
where tell me then
it tells us the number on the Periodic Table and it also tells us how many protons and nuetrons and electrons are in the atom within the nuecles.
it tells us that their chemical properties are similar, and in many cases follow a trend.
we use the periodic table because it helps us with the atoms and electrons it tells us the mass number atomic number and the symbol
Periods in the periodic table tell you the number of electron shells an element has. As you move across a period from left to right, the number of protons, electrons, and valence electrons increases by one, resulting in elements with similar chemical properties being grouped together.
