It is called a horizontal line!
A vertical stack of cells is called a column. A horizontal line of cells is called a row.
There are 7 metalloids in periodic table. They are present on zigzag line in periodic table.
The zigzag line is called the zigzag line or is sometimes referred to as the Hays-McDaniel line
None! They r called Metalloid.
