An atom is the complete building block of all elements, each element has its own unique atomic formation. An atom consists of a nucleus with a cloud of electrons surrounding it, and is electrically neutral unless ionised. The nucleus at the center of the atom consists of protons which are positively charged, and neutrons which are uncharged, and these are all bound together by the 'strong nuclear force', which has a very short range so it only is effective within the nucleus. Each chemical element (see the Periodic Table) is defined by a unique number of protons called the Atomic Number, and can have a variable number of neutrons so that there are different isotopes of the same element. The number of electrons in the atom is equal to the number of protons in the nucleus, unless the atom has been ionised.

BlakeAn atom is the basic unit of matter composed of a nucleus containing protons and neutrons, surrounded by electrons. The nucleus is the central core of an atom containing protons and neutrons, while electrons orbit around it. In summary, the nucleus is a part of an atom, specifically the central region, whereas an atom is the whole structure consisting of the nucleus and electrons.

What is the mass defect formula used to calculate the difference in mass between the nucleus of an atom and the sum of its individual nucleons?
The mass defect formula is used to calculate the difference in mass between the nucleus of an atom and the sum of its individual nucleons. It is calculated by subtracting the actual mass of the nucleus from the sum of the masses of its individual protons and neutrons.
What is the difference between a proton and an electron?
A proton is a positively charged subatomic particle found in the nucleus of an atom, while an electron is a negatively charged subatomic particle that orbits the nucleus.
What statement best describes the density of an atom's nucleus?
The nucleus of an atom is highly dense, containing nearly all of the atom's mass in a tiny volume. It consists of protons and neutrons packed tightly together. The density of the nucleus is about 100,000 times greater than the overall density of the atom as a whole.
What is located in between the electrons and nucleus of an atom?
The nucleus of an atom contains protons and neutrons, while the electrons orbit around the nucleus in energy levels.
Do protons orbit the nucleus in an atom?
No, protons do not orbit the nucleus in an atom. They are located within the nucleus along with neutrons. Electrons are the particles that orbit the nucleus in an atom.
