It depends on the atom and isotope. In the most common isotope of hydrogen, there are no neutrons. In other light elements, the numbers of protons and neutrons are often equal. In heavier elements, there are more neutrons than protons in most isotopes.
The number of electrons should = the number of protons.
No, the overall charge of an atom is negative only if the number of electrons is greater than the number of protons. An atom becomes negatively charged when it gains extra electrons, causing an imbalance in the positive charge of the protons and the negative charge of the electrons.
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
False. An atom is neutral if it has an equal number of protons and neutrons
The number of electrons should equal the number of protons, otherwise you have an ion.
The number of electrons should = the number of protons.
No, the overall charge of an atom is negative only if the number of electrons is greater than the number of protons. An atom becomes negatively charged when it gains extra electrons, causing an imbalance in the positive charge of the protons and the negative charge of the electrons.
An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
False. An atom is neutral if it has an equal number of protons and neutrons
In any neutral atom, the number of protons = the number of electrons.
An atom has the same number of electrons as it does protons, and the number of protons determines what element it is.
The number of protons must equal the number of electrons in an atom for it to have no charge. Protons are positively charged particles, and electrons are negatively charged particles. A balanced number of protons and electrons results in an atom with a neutral overall charge.
The nucleus of an atom contains only protons and neutrons; there are never any electrons in the nucleus. The number of neutrons is generally equal to or greater than the number of protons.
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
