What are the elements below and to the left of the zigzag line called?
All of the transition elements are metals. Any element to the left of the zigzag line in the periodic table that runs from boron to astatine. All metals except mercury are solids at room temperature and pressure.
What is the purpose of zigzag line?
The zigzag line in the periodic table is used to separate the metals and the nonmetals. In addition, the elements that touch the zigzag line are categorized as metalloids.
In which side of zigzag line are metals?
left
What is the purpose of the staircase line?
The staircase line indicates the position of the metalloids in the Periodic Table.
Which elements are present near the zigzag line?
The bordering elements along the zig-zag line are the metalloids. These are Antimony (Sb), Germanium (Ge), Boron (B), Silicon (Si), Arsenic (As), Tellurium (Te), Polonium (Po). They show intermediate properties and are called as metalloids or semi-metals.
What is the first element at the top of the stair step?
boron
What are borderline elements?
The borderline elements – boron, silicon, germanium, arsenic, antimony, tellurium and polonium – are intermediate in properties and are called metalloids or semi-metals. As you have seen in Chapter 3, metals tend to lose electrons while forming bonds, that is, they are electropositive in nature.
What does the zigzag line separate?
The line of separation between metals and nonmetals is the zigzag line. This zig zag line contains metalloids. These include antimony, germanium, boron, silicon, arsenic, tellurium and polonium. The zigzag line in the periodic table separates metals from nonmetals.
What is the zigzag?
1 : one of a series of short sharp turns or angles in a line or course. 2 : a line, path, or pattern with a series of short sharp angles. zigzag.
Which is a property of most metals?
In addition to conducting electricity, many metals have several other shared properties, including those listed below.
- Metals have relatively high melting points.
- Most metals are good conductors of heat.
- Metals are generally shiny.
- The majority of metals are ductile.
- Metals tend to be malleable.
