f. 1 and 3

Answer 1

Subatomic particles including protons, neutrons, and electrons make up atoms. Protons and neutrons have similar masses (around 1 amu) and are located in the nucleus, while electrons are lighter and found in orbitals around the nucleus.

Step-by-step explanation:

Understanding Subatomic Particles

Subatomic particles are the building blocks of atoms, and these include protons, neutrons, and electrons. Protons have a positive charge and a mass of approximately 1 atomic mass unit (amu). Neutrons are neutral with a similar mass to protons, around 1 amu. Electrons have a negative charge and are much lighter, with a mass about 1/1800th that of a proton.

The mass of these particles is expressed in amu, where 1 amu is defined as one-twelfth the mass of a carbon-12 atom. In terms of their location, protons and neutrons are located in the nucleus of an atom, which is at the center, whereas electrons are found in defined spaces, or electron clouds, around the nucleus.

The number of protons in an atom's nucleus defines the element, while the number of electrons determines its charge if the atom is an ion. The sum of the number of protons and neutrons is called the atomic mass, while the defined space around an atom's nucleus where an electron is most likely to be found is known as an electron cloud or orbital.
