The rows on the periodic table are called periods and the columns are called families
The columns represent the groups and the rows represent the periods that the elements are classified under.
each periodic table has different color.
It's outer electron orbital
The horizonal rows and the vertical columns are called groups
hi, the 65 elements found on earth are arranged in order of increasing atomic number (Z) as you go from left to right across the table. We call the horizontal rows periods a…nd the vertical rows groups. What is said above is true but doesn't answer your question (and there are a lot more than 65 elements in the periodic table!). The row in which an element is found indicates the number of 'shells' which are filled. So Hydrogen and Helium are in row 1 so only the innermost 1s shell is filled. The electron configuration of elements in row 2 begins with Lithium - 2.1 - and ends with Neon - 2.8. And so on...
about the substances physical state, chemical properity(boiling point , melting point),etc..
The horizontal lines of the periodic table represent the number of proton shells the element has.
The elements are arranged in horizontal rows and vertical columns, the rows are called periods and the columns are called groups or families. All the elements of the same grou…p have similar chemical and physical properties. The periods all show a similar pattern, with metallic elements on the left transitioning to nonmetallic elements on the right of the periodic table.
Yes! The elements are arranged in horizontal rows and vertical columns to represent what is called the periods on the periodic table.
It gives us a classification about the elements based on their chemical and physical properties.
We can find the period, the group (and the general properties in this group), atomic number, atomic weight, chemical symbol, etc.
it represent the protons
The rows (periods) work out to be the energy levels, ex. if an element is in period 5, it has 5 energy levels.
The rows in a periodic table are called "Periods".
