Question

When something asks for atoms or molecules, what do we use?

1) Atoms
2) Molecules
3) Both atoms and molecules
4) None of the above

Answer 1

The choice between atoms or molecules depends on the specific context.1)Atoms are the smallest units of an element, while molecules are groups of two or more atoms bonded together.

Step-by-step explanation:

When we are asked to consider atoms or molecules, the choice between the two depends on the context of the question. An atom is the smallest unit of an element that retains all of the properties of that element.

While a molecule is a group of two or more atoms bonded together. For example, hydrogen and oxygen atoms combine in a 2:1 ratio to form a water molecule (H2O), which is composed of three atoms.

An atomic mass unit (amu) is a unit of mass equal to one-twelfth of the mass of a carbon-12 atom. Its abbreviation is u. The atomic mass of an element, given in atomic mass units, is roughly equivalent to the sum of the masses of protons and neutrons.

In an atom of that element. Different isotopes of an element have different masses which are estimated in whole numbers.When dealing with substances, we rarely measure individual atoms or molecules but rather a large number of them.

The 'mole' is a unit that allows chemists to convert between the microscopic world of atoms and molecules and the macroscopic world of grams and liters. It relates quantities of substances on a manageable scale.
