Peso atómico

The video explains the difference between atomic mass and atomic weight. Atomic mass refers to the mass of atoms of a specific isotope, while atomic weight is the average mass of an element's isotopes. Unlike atomic mass, atomic weight can vary due to changes in isotope proportions.

What does atomic mass specifically refer to?

• The mass of a specific isotope's atoms

• The average mass of all isotopes of an element

• The weight of an element in a compound

• The density of an element

Which of the following is true about atomic mass?

• It is the sum of protons and neutrons

• It refers to the mass of a specific isotope

• It varies with different samples

• It is the same as atomic weight

How is atomic weight different from atomic mass?

• Atomic weight is constant for all samples

• Atomic weight refers to a specific isotope

• Atomic weight is the average mass of isotopes

• Atomic weight is the same as atomic number

Why can atomic weight vary between samples?

• Due to changes in temperature

• Due to changes in the element's atomic number

• Because of different chemical reactions

• As a result of varying proportions of isotopes

What factor causes the atomic weight of an element to change?

• The number of electrons

• The proportion of its isotopes

• The element's chemical properties

• The element's position in the periodic table
