When you round 10.81 to the nearest integer, the result is 11.

When you subtract the number of protons (equal to the atomic number) from the atomic mass, the result is 6.

A particle that is not neutral (has either more or less electrons) is known as an ion.

Number of Neutrons- The number of neutrons in an atom is equal to the number of protons in an atom subtracted from the mass of the atom rounded to the nearest integer.

The greater the density of an element is, the "heavier" the element is.

Color- The color of an element refers to its physical reflection of light under normal conditions.

This is true because both neutrons and protons have an atomic weight of approximately 1 AMU, the number of neutrons listed on the element fact sheets is only valid for the most abundant isotope of any element.

For example, boron (B) has an atomic mass of 10.81 and an atomic number of 5.

For example, the element aluminum (Al) is spelled aluminum in the United States, but is spelled (and pronounced) aluminium in most other English-speaking countries, including Great Britain, Canada, and Australia.

A naming dispute has occurred between the American Chemical Society (ACS) and the International Union for Pure and Applied Chemistry (IUPAC) over elements 104-109.

Atomic masses used on this periodic table are from the IUPAC 1995 recommendations.
