Which more common element touches the staircase but is not highlighted green? 1 Answer. Nathan L. These elements are called metalloids .
What do the elements that touch the staircase on the periodic have in common?
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.
Which type of elements are found to the right of the staircase?
Metals and Nonmetals
The nonmetals are located to the right of the stair-step line on the periodic table. Metals tend to lose electrons in chemical reactions, forming positive ions.
Why are the elements at the staircase special?
It is more of a nonmetal than a metal , but it has some of the properties of both metals and nonmetals. The elements to the immediate left of the line tend to lose electrons more easily than gain them. These elements have relatively low electronegativities.
What is the only element located on the left of the staircase that is not considered a metal?
HYDROGEN is the only non-metal element that is not located with the rest. 13. Where are the metalloids found and how many of them are there? The metalloids are found directly around the staircase.
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. ... The metalloids (aka semi-metals) are B, Si, Ge, As, Sb, and Te.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine , the rarest naturally occurring element on Earth.
What do the stairs indicate?
Even the language surrounding stairs and how we talk about stairs is exceedingly symbolic — ascent, descent, climb, step, levels — these are all words associated with journey, progress, and growth, and not just in terms of the physical act, but also in terms of the emotional and spiritual connotations of journeying.
What is the most abundant metalloid in the universe?
| Question Answer | _______________ is in most of the compounds that make up living things. carbon | The most abundant metalloid in the universe is _______________. silicon | Elements on the left side of the periodic table are classified as ____________________. metals |

What is the only metal touching the zig zag line?
Metalloids – are found along the zigzag line on the periodic table. The only exception is Aluminum . It is considered to be a metal even though it lies along the zigzag.
What does the 6 represent in carbon?
It has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons . Since carbon is in the second row (or second period), it has 2 electron orbits. Use the clay to make your protons and neutrons in the nucleus.
Is silicon a metal?
For this reason, silicon is known as a chemical analogue to carbon. ... But unlike carbon, silicon a metalloid — in fact, it’s the most common metalloid on earth. “Metalloid” is a term applied to elements that are better conductors of electron flow — electricity — than nonmetals, but not as good as metals.
What is the simplest substance?
An element is the simplest form of matter that has a unique set of properties. Examples of well-known elements include oxygen, iron, and gold (see the figure below). Elements cannot be broken down into a simpler substance. Likewise, one element cannot be chemically converted into a different element.
What is the least metallic element?
The least metallic or most non-metallic element is fluorine . Halogens near the top of the periodic table are the least metallic elements, not the noble gases.
What can be found in the left side and in the right side of the stair step?
With the exception of HYDROGEN, the elements on the left side of the periodic table are METALS . Elements on the right side of the periodic table are NONMETALS. The staggered stair step on the periodic table divides the metals from the nonmetals. Metalloids are located on the stair step.
What the elements located to the left of the staircase are called?
The elements to the immediate left of the “staircase line” are called “ semi-metals” or “metalloids” because they can behave chemically as both metals or nonmetals. The metallic elements are characterized by a metallic luster and high electrical and thermal conductivity.
