Front

What is the mass of a neutron compared to an electron?

Back

The mass of a neutron is about 1838 times the mass of an electron.

Front

What led to the development of the modern periodic table?

Back

The modern periodic table was developed as a result of scientists attempting to arrange the information known to them, organizing the elements in a way that relates their position with the structure of the atoms, and recognizing the periodic nature of the elements.

Front

What best describes metallic bonds?

Back

Metallic bonds are best described as metal atoms attracting their sea of shared electrons.

Front

How does the modern periodic table arrange elements?

Back

The modern periodic table arranges elements according to their atomic numbers.

Front

What does covalent bonding form?

Back

Covalent bonding forms molecules.

Front

What does ionic bonding form?

Back

Ionic bonding forms crystals.

Front

What is the law of octaves in relation to the periodic table?

Back

The law of octaves is an early attempt to classify elements based on their properties and atomic masses.

Front

What are diatomic molecules?

Back

Diatomic molecules are molecules composed of only two atoms, which can be of the same or different chemical elements.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have an unequal distribution of electric charge, while nonpolar molecules have an equal distribution.
