What is the bold staircase line on the periodic table?
The staircase line indicates the position of the metalloids in the Periodic Table.
What does the dark stair step line separate on the periodic table?
Draw a HEAVY BLACK stair step line (using a marker) on your periodic table to show the location of the metalloids. This line also separates the metals from the non-metals.
What is the stair step line on a periodic table called?
metalloids
On the periodic table, the elements colored yellow, which generally border the stair-step line, are considered to be metalloids. Notice that aluminum borders the line, but it is considered to be a metal since all of its properties are like those of metals.
What does the line in the periodic table mean?
One line separates metals and metalloids; the other metalloids and nonmetals.
What is the only metal touching the staircase?
What is the only metal touching the staircase? Polonium is a metal and there’s not enough astatine to actually tell, but it is not included in the metalloids. Aluminum is under the stair-step line, but is very much a metal. The metalloids (aka semi-metals) are B, Si, Ge, As, Sb, and Te.
What is the purpose of the staircase on your periodic table?
They form the staircase that represents the gradual transition from metals to nonmetals. These elements sometimes behave as semiconductors (B, Si, Ge) rather than as conductors. Metalloids are also called “semimetals” or “poor metals.”
Which more common element touches the staircase but is not highlighted green?
Which more common element touches the staircase but is not highlighted green? 1 Answer. These elements are called metalloids.
What does the zigzag line in periodic table imply?
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 first element at the top of the stair step?
When you move from left to right or bottom to top, the less metallic an element is. The hard line between the two groups is the stair step starting in front of boron and zigzagging between elements to astatine. The elements on the left are considered metals and the ones on the right are considered nonmetals.
What does the stair step line on the periodic table tell you?
What does the stair- step line on the periodic table tell you? The stair step that is seen in the group 3-7 of the representative element ( the right most side of the Periodic Table) divides the table of elements into two.. The right side of the stairs are the non metals (eg is the C, S, Cl etc..)
What kind of elements border the stair stepped line?
The elements that border the stair-stepped line are classified as metalloids. The metalloids, or semimetals, have properties that are somewhat of a cross between metals and nonmetals. Nonmetals. Except for the elements that border the stair-stepped line, the elements to the right of the line are classified as nonmetals (along with hydrogen).
Which is the right side of the stair step?
The stair step that is seen in the group 3-7 of the representative element separates the metals from the non-metals. The right side of the stairs are the non-metals (Carbon, Phosphorus, Sulphur, Chlorine, etc.) They possess the characteristic of non-metals such as poor conductivity of heat & electricity, etc.
What are the metalloids around the stair steps?
And those around the stair steps are the metalloids (eg. Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium) have a half characteristic of metals and non metals.. >They are semi conductor of heat and electricity and reacts as metal or non metal depending on the element you bond in them..
