The PERIODIC TABLE / ACIDS & BASES

What types of elements have properties of the other two groups? (They're along the zigzag line)

In the periodic table, elements are arranged vertically in columns called _?_.

What does the zigzag line on the periodic table do?

Which of these elements would be the most chemically similar?

These types of elements are typically not malleable, ductile, or shiny and are poor conductors.

What type of compounds react with metals and carbonates, taste sour, and have a pH less than 7?

An acid has a pH of 5. A base has a pH of 9. If you mix them together in a beaker, what will the pH be at the end?

Elements are arranged by _?_, because within a period these change in a predictable way.

In the periodic table, elements are arranged in horizontal rows called _?_.

Most elements are _?_. (Usually solid, shiny, ductile, malleable, and good conductors.)

An element's chemical properties are determined by the number of its _?_.

On the periodic table, how does atomic number change as you read from left to right?

What is labeled "X"? (It's the proton number)

Elements in a group have similar _?_ because they have the same number of valence electrons.

Who organized the first Periodic Table of Elements?

What is labeled "X"? (It's related to the proportion of isotopes that exist for an element)

What type of compounds feel slippery, taste bitter, and have a pH greater than 7?

When acids and bases react they always produce __?__.

What is labeled "X"?
