What is the staircase on the periodic table called?
What is the staircase on the periodic table called?
Many of the elements that touch the staircase are called metalloids, and these exhibit both metallic and nonmetallic properties. The right side of the periodic table has a dividing line resembling a staircase. To the left of the staircase lie the metals, and to the right of the staircase lie the nonmetals.
Which elements are found around the staircase?
Explanation: The elements along side the line are metalloids. They have both metallic and nonmetallic character.
What is the black line on the periodic table?
On many periodic tables, a jagged black line (see figure below) along the right side of the table separates the metals from the nonmetals.
What does a line between two nonmetals represent?
Covalent bonds generally form when a nonmetal combines with another nonmetal. The shared electrons act like they belong to both atoms in the bond, and they bind the two atoms together into a molecule. The shared electrons are usually represented as a line (—) between the bonded atoms.
What is the dividing line between metals and nonmetals called?
This line has been called the amphoteric line, the metal-nonmetal line, the metalloid line, the semimetal line, or the staircase. It is also erroneously referred to as the Zintl border or the Zintl line.
What is a dividing line called?
more The line that separates the numerator and the denominator in a fraction. Also called a Vinculum in some countries.
Can you cross an unbroken white line?

What is another symbol for multiplication?
The multiplication sign, also known as the times sign or the dimension sign, is the symbol ×, used in mathematics to denote the multiplication operation and its resulting product. While similar to a lowercase X (x), the form is properly a four-fold rotationally symmetric saltire.
What signs are used for division?

What is division sum?
Therefore, to check a division sum, add the remainder to help product of divisor and quotient. The result should be equal to the dividend. Properties of division: When zero is divided by a number the quotient is zero.
