is the atomic number the same as the number of neutrons?

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. ... The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.

Atoms of the same element that differ in their numbers of neutrons are called isotopes. ... Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.

Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well.

Atomic number. The number of protons in an atom of an element is its atomic number . Remember that: all atoms of a given element have the same number of protons.

Explanation: Isotopes are atoms of the same element (same atomic number) but with a different number of neutrons (different atomic mass).

Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.

Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes.

Answer and Explanation: All atoms of an element have the same number of protons. The number of protons in an element is a primary identifier known as its atomic number.

The atomic number and the number of protons are the same. How do the number of protons, number of neutrons, and the mass number related to each other? What determines the identity of the atom? The atomic number tells the number of positively charged __________ in the nucleus of an atom.

Atomic number and protons After the discovery of protons , scientists realised that the atomic number of an element is the same as the number of protons in its nucleus . In the modern periodic table, the elements are arranged according to their atomic number - not their relative atomic mass .

Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical. There's more to the atom than the electrons. There's also the nucleus. ... We refer to the atoms of the same element with different numbers of neutrons as "isotopes".

Not all the atoms of an element need have the same number of neutrons in their nuclei. ... The three share the place in the periodic table assigned to atomic number 1 and hence are called isotopes (from the Greek isos, meaning “same,” and topos, signifying “place”) of hydrogen.

The atoms of different elements have different numbers of electrons, protons, and neutrons. Every element is unique and has an atomic number. That number tells you the number of protons in every atom of the element. The atomic number is also called the proton number.

Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).

Protons and neutrons make up the nucleus of an atom. All protons are identical to each other, and all neutrons are identical to each other.

Atoms of the same element that differ in their numbers of neutrons are called isotopes. ... Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.
