Jul 29, 2022 · In order to be neutral, an atom must have the same number of electrons and protons. Atoms—and the protons, neutrons, and electrons that compose them—are extremely small. For example, a carbon atom weighs less than 2 × 10 −23 g, and an electron has a charge of less than 2 × 10 −19 C (coulomb).

In an easy example, you may be asked to simply determine the number of protons for the given element. For example, how many protons does Ca have? For this, you just need to look up the atomic numberof Ca, which we find, from the periodic table, that it is 20. Therefore, Ca has 20 protons. Do not get confused if the element is given with some other ...
The first thing you need to remember here is the charge of the ion is a result of an imbalance between the number of protons and electrons. If it is a cation, then the positive indicates how many more protons it has compared to the number of electrons. For anions, the charge tells how many extra electrons there are compared to the number of protons...
The most important part you will need for calculating the number of neutrons is that together with protons, they make the atomic mass of the given isotope. So, if we have the mass number of the given isotope, we can easily determine the number of its neutrons. For example, how many neutrons does the 65Cu isotope have? The first thing, again, is to ...
Sep 1, 2024 · The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.

Jun 2, 2019 · Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen).

Like protons, neutrons are bound into the atom's nucleus as a result of the strong nuclear force. Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron).
Aug 26, 2020 · Neutral atoms have the same number of electrons and protons. Atoms of an element that contain different numbers of neutrons are called isotopes. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons.
Today, they agree that atoms have a positively-charged nucleus made of protons and neutrons, and negatively-charged electrons that orbit the nucleus in shells.
