Answer:
The structure of a copper atom can be determined by its atomic number and atomic mass.
The atomic number of copper is 29, which means it has 29 protons in its nucleus. Protons have a positive charge and determine the element's identity.
The atomic mass of copper is 64, which is the sum of protons and neutrons in the nucleus. Neutrons have no charge and help stabilize the nucleus.
To find the number of neutrons in a copper atom, subtract the atomic number from the atomic mass:
64 - 29 = 35 neutrons
Therefore, a copper atom has 29 protons, 35 neutrons, and 29 electrons. Electrons have a negative charge and orbit the nucleus in energy levels or shells.
The electron configuration of copper can be represented as 2, 8, 18, 1. This means there are 2 electrons in the first energy level, 8 electrons in the second energy level, 18 electrons in the third energy level, and 1 electron in the fourth energy level.
The structure of a copper atom can also be visualized as a nucleus at the center with 29 protons and 35 neutrons. Surrounding the nucleus, there are energy levels or shells containing the electrons. The first energy level contains 2 electrons, the second energy level contains 8 electrons, the third energy level contains 18 electrons, and the fourth energy level contains 1 electron.
In summary, a copper atom has a structure consisting of a nucleus with 29 protons and 35 neutrons, surrounded by energy levels or shells containing 29 electrons arranged in the electron configuration 2, 8, 18, 1.
