Periodic table and bonding

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs between a metal and a nonmetal, where electrons are transferred from one atom to another.

Front

What is the atomic number of an element?

Back

The atomic number of an element is the number of protons found in the nucleus of an atom of that element.

Front

Which element is in group 2, period 6 of the periodic table?

Back

Barium (Ba) is the element found in group 2, period 6.

Front

What do negative ions do with electrons?

Back

Negative ions tend to gain electrons.

Front

What is the difference between a metal and a nonmetal?

Back

Metals are typically good conductors of heat and electricity, while nonmetals are poor conductors and can be gases, liquids, or solids at room temperature.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two nonmetals share electrons.

Front

What is the role of protons in an atom?

Back

Protons determine the atomic number of an element and contribute to the positive charge of the nucleus.

Front

What is the difference between atomic mass and atomic number?

Back

Atomic mass is the weighted average mass of an element's isotopes, while atomic number is the number of protons in the nucleus.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.
