Periodic Table Flashcard

Front

What are non-metals?

Back

Non-metals are elements that are usually gases or brittle solids at room temperature, and they do not conduct electricity well. They are found on the right side of the periodic table.

What is the atomic mass of titanium?

Back

The atomic mass of titanium is 47.867.

Front

What are isotopes?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses.

Front

How many protons does bromine have?

Back

Bromine has 35 protons.

Front

What are metals?

Back

Metals are elements that are typically shiny, good conductors of heat and electricity, and are malleable and ductile.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

Front

What are metalloids?

Back

Metalloids are elements that have properties intermediate between metals and non-metals. They can conduct electricity better than non-metals but not as well as metals.

Front

What is the significance of atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity and its position in the periodic table.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is a substance formed when two or more different types of atoms bond together.

Front

What are noble gases?

Back

Noble gases are a group of elements in Group 18 of the periodic table that are characterized by their lack of reactivity due to having a full valence shell of electrons.
