Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that. This also means that the atomic weight of the elements gets larger and larger in each period.
Periods and groups are both ways of organizing elements on the Periodic Table. Periods are horizontal rows that indicate the number of electron shells an element has, while groups are vertical columns that show elements with similar chemical properties due to having the same number of valence electrons.
Elements in a Period Have how many shells for the Electrons in Common. eg. period 3 elements all have 3 shells.
The number of electrons in a shell goes like this:
2,8,8,18,18,18,3.

The horizontal rows in a periodic table are called groups?
Actually, the horizontal rows in a periodic table are called periods, not groups. Groups are the vertical columns that share similar chemical properties.
What are groups and periods in periodic table?
The columns are called groups and rows are called periods. There are 18 groups and 7 periods.
How many period are there in the Modern Periodic Table?
The Periodic Table has 18 groups and 7 periods.
What is periodic table arrangements?
Periodic table is arranged in rows and columns. there are 7 periods and 18 groups.

The periodic table
How many periods and groups are there in the periodic table?
There are 18 groups and 7 periods in the periodic table. Groups indicate the number of valence electrons an element has, while periods indicate the number of electron shells an element has.

What are the classification of element in a periodic table?
periodic table is classified into groups and periods.There are 18 groups and 7 periods in periodic table.
What are the horizontal rows on the periodic table?
The rows (Horizontal) are called Periods and the Columms (Vertical) are called Groups.
What are the groups and period of the periodic table?
Groups are the vertical columns. Periods are the horizontal rows in the periodic table.
What are the horizontal groupings in the periodic table named?
The horizontal lines are called "periods" and show how many "shells" each atom hasThe horizontal rows in the periodic table are called periods. The vertical columns are called groups.
How much periods does a periodic table have?
A periodic table has seven periods. It also has 18 groups and 4 different families.
The horizontal rows in a periodic table are called groups?
Actually, the horizontal rows in a periodic table are called periods, not groups. Groups are the vertical columns that share similar chemical properties.
How many periods are on the periodic tables?
7The Periodic Table has 7 periods and 18 groups.
