The number of protons that are in the atom's nucleus gives the atom its atomic number.
Every element has a specific number of protons. Every hydrogen atom has exactly one proton, every helium atom has exactly two protons, etc.
This is a easy question. This one is based on chemical elements. We make atomic number on number of protons.
The number of protons in the nucleus.
Atomic Number
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
the number of atoms is 19 an 20
An atom is electrically neutral; it has the same number of positively charged protons as it has negatively charged electrons. If an atom either gains or loses one or more electrons, then it will have an electric charge, and will be an ion.
Scientists have designated electrons as having a negative charge and protons as having a positive charge. One positive proton can hold one negative electron in orbit. Thus, an atom with one proton in its nucleus normally will have one electron in orbit (and be labeled a hydrogen atom); an atom with ninety-four protons in its nucleus will normally have ninety-four electrons orbiting it (and be labeled a plutonium atom).
The number of protons in an atom is the atomic number. It tells you which element the atom is.
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
the one thing that gives an atom its identity is the mass number and the atomic number
the number of protons in one element determines the atom's
The number of protons determines the element. So when neutrons are added, there is no change in the number of protons and helium atom is unchanged.
the number of atoms is 19 an 20
It depends on what atom. The number of protons in an atom determines which element it is and the properties it has. Hydrogen atoms will always have one, and only one, atom, while Neodymium atoms will have exactly 60 atoms. If the number of protons was different, say 61, the atom would be a different element, specifically Promethium. The number of protons for an element is also its atomic number.
The number of protons in the nucleus of an atom determines its identity as a particular element. The number of protons is the element's atomic number, and is unique to each element. For example, the atomic number of oxygen is 8, while the atomic number of carbon is 6.
The number of protons. One proton and you have Hydrogen, two - Helium, three - Lithium, and so on. The atomic number is defined by how many protons are in an atom.
An element is the type of substance it is, for example, oxygen, hydrogen, etc. An atom is the combined particle consisting of electrons spinning around a nucleus, which is made up of protons and neutrons. The number of protons in an atom, not element, determines the type of element it is. If the atom looses a proton, then the element changes to a different one.
Atoms are normally identified according to the element of which that atom is an example. And that, in turn, is determined by the number of protons in the atom's nucleus. So, any atom that has just one proton is a hydrogen atom. If it has two protons it is a helium atom. And so forth.
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
