If the stair step line on Periodic Table divide, then the elements to the left of this line are metals, except hydrogen
The elements on the left of the line are 'Metals' and the ones on the right are 'Nonmetals' with the exception of Hydrogen in Gr 1
it divides the metals from the nonmetals.
it is called the staircase...
Metals and non-metals
it represents the division of the metals from the nonmetals
The zig-zag line (or sometimes known as the staircase) separates the metals in the periodic table from the non-metals. Metals are present on the left of the zigzag line and non metals to its right. The elements on the staircase are known as metalloids.
There is a staircase (or a zigzag line) that runs through group 13 to group 17. Elements to the left of this are metals.They are located to the left of the bold line on the right side of the periodic table. The line looks like a series of steps going to the right and down.
You take the atomic mass (the small number in the upper left corner of the square in the periodic table) and subtract the atomic number from it (the big bold number on the periodic table)
There is also usually a bold zig-zag line running from just left of boron (#5) to the lower right hand corner of the table. Some people think this line looks like a staircase, so the scientific community calls it the staircase. This line separates elements that have been observed to be metals from those that have been observed to be non-metals. Elements touching the staircase often have some properties of both metals and non-metals, so they are called semi-metals or metalloid
They occupy all but the top right corner of the table.
I am sorry but while you may see a bold staircase in the periodic table, this is not a universally recognized concept. We do not know what you are talking about and therefore can not answer your question.

Look up "periodic table of elements." the elements on the left of the bold line and right are separated based on this. It would be an Ionic Compound (metal/non-metal mixture) "SodiumChloride"
Metals make up most of the Periodic Table. They are located on the left side of the table as well as in the middle of the table. Metalloids occupy the spots that trace the bold zig-zag line present on many tables. Non-metals are located on the right side of the table.

It is a metal. All metalloids are located touching the bold line on the periodic table (except aluminum)
They are called groups or families. Often the elements that are found in the same group as each other have similar chemistry and reactivity.Each column is named as follows, going from left to right across the Periodic Table (see the Web Links to the left for a periodic table).The names in bold are the most very commonly used names (some of the other names are not very often used).

1 is least massive leading to the manmade elements in the 100's which are most massive, and also by gasses, non-metals, metaloids and metals'
