What else can I help you with?
The term element refers to atoms that have the same number of?
protons in the nucleus. This number is known as the atomic number and distinguishes one element from another. Elements are organized on the periodic table based on their atomic number.
What is the term for the value that indicates the number of protons for an atom of a given element?
The atomic number is the number of protons in an atom of an element.
What is the mass number minus the atomic number called?
Nucleon Number (total number of protons and neutrons)
What does the term mean atomic number mass number?
The atomic number represents the number of protons in an atom's nucleus, determining the element's identity. The mass number is the sum of the protons and neutrons in an atom's nucleus, giving the atom its mass.
Define the term mass number?
Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered. I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.
Why mass number denoted by A?
Mass number is the total number of protons and neutrons. because the nucleus consists of protons and neutrons only, the sum of protons and neutrons is the total number of ALL the nucleons. note the term "ALL" here.. this is the reason why mass number is denoted as "A".
Why is proton number of an atom of an element different from the nucleon number of an atom of an element?
The difference between proton number (which is atomic number) and nucleon number, which is the number of protons and neutrons in an atom's nucleus, is the number of neutrons in the nucleus of a given nuclide. Nucleons are the components of an atomic nucleus. We know that both protons and neutrons make up an atom's nucleus. So the number of nucleons, which is the number of protons and neutrons, minus the number of protons, will equal the number of neutrons in the atomic nucleus.
What is the number protons in the nucleus?
The number of protons in the nucleus is equal to the atomic number of that atom. Said another way, the atomic number of any element is the number of protons in the nucleus of any atom of that element.It might be helpful to consider some examples, and if we look at mercury, we'll see it has an atomic number of 80. All atoms of mercury have 80 protons in them. Aluminum has the atomic number of 13, so all atoms of it have 13 protons in them. Uranium, which has atomic number 92, has 92 protons in all of its atoms.The number of electrons and neutrons in a given atom of a given element can vary for a number of reasons, and these characteristics are considered separately. The number of electrons in any atom will match the number of protons in the nucleus of that atom only if the atom is a neutral one. Some atoms loan out or borrow electrons, and then they become what are called ions. The number of neutrons can vary, too, and we use the term isotope to talk about atoms of a given element having different neutron counts.The atomic number indicates the number of protons in an atom's nucleus.The number of protons in the nucleus is the atomic number of the atom.
What is the name for the number of protons and neutrons in an atom?
The number of protons in a nucleus of an atom is called the "proton number", strangely enough. If you are a physicist, you will most likely prefer this term. Chemists however, would rather call it "atomic number".
Which particle determines the nuclear charge?
Protons determine the nuclear charge of an atom. Each proton carries a positive charge and is located in the nucleus of an atom. The number of protons in an atom determines its atomic number and therefore its nuclear charge.
How is the atomic number of an atom determined?
The atomic number of an element is determined by the number of protons in its nucleus. It's that simple. Note that the number of electrons will only equal the number of protons in an atom that is neutral, and can vary. The number of neutrons can vary as well, and we use the term isotope to differentiate between atoms of a given element with different numbers of neutrons in their nucleus.
What term best indicates the total number of neutrons and protons in a particular isotope of an element?
The atomic mass number is the sum of the protons and neutrons of an element. The protons are given by the atomic number, so the neutrons can be found by subtracting the mass number by the atomic number. Both the mass and atomic numbers can be found on the periodic table.
