Step 1

Carbon, regardless of its isotope, always has an atomic number of 6. Therefore, the number of protons in carbon-11 is 6. \[ \text{Number of protons} = \text{Atomic number} = 6 \] Show more…

Key Concepts

Isotopes

Isotopes are different forms of the same element that have the same number of protons but differ in the number of neutrons. This concept is essential in understanding variations in the atomic mass of an element while its chemical properties remain largely unchanged.

Atomic Structure

Atomic structure refers to the organization of an atom, which primarily consists of protons, neutrons, and electrons. The protons and neutrons form the nucleus, which contains most of the atom's mass, while the electrons orbit the nucleus and are responsible for chemical behavior.

Atomic Number and Mass Number

The atomic number of an element is the number of protons in its nucleus and defines the element's identity. The mass number is the total number of protons and neutrons in the nucleus. For a neutral atom, the number of electrons equals the number of protons.
