Atoms of an element have a certain number of?

A specific number of either protons or electrons is a characteristic of atoms of a particular element.


What is a characteristic property of an element?

A characteristic property of an element is its atomic number, which determines the element's identity on the periodic table. Each element has a unique number of protons in its nucleus, which is constant for that element regardless of its chemical state or conditions.


Which subatomic particles identifies an atom as that of a particular element?

The number and arrangement of protons in an atom's nucleus determine the element it is. Each element has a unique number of protons, known as the atomic number, which distinguishes it from other elements.


What features of an atom identifies it as a particular element?

The features that identify an atom as a particular element are primarily its atomic number, which is determined by the number of protons in its nucleus. Each element has a unique atomic number; for example, hydrogen has one proton, while carbon has six. Additionally, the arrangement of electrons and the element's isotopes can also influence its chemical properties, but the atomic number is the definitive characteristic that distinguishes one element from another.


What particles will always have a constant number in one particular element?

Protons remain constant for a specific element, as they determine the element's identity. Electrons can vary but generally match the number of protons for a neutral element. Neutrons can vary slightly within isotopes of an element.


What is a characteristic of an element?

One characteristic property of an element is the number of electrons it has.


Which subatomic particle identifies an atom of a particular element?

It's the count of one of the subatomic particles in the nucleus, the proton, that is significant in this regard. For example, an atom is hydrogen if and only if it has one proton in its nucleus. It is neon if and only if it has ten protons in its nucleus.


What is the number of atoms in an element?

The number of atoms in an element depends on WHAT element AND how much of that element.


What characteristic of an element tells the number of protons in its nucleus?

Its atomic number.


What did you find determines the element?

The number of protons is characteristic.


The number of positively charged particles in atoms of a given element?

The number of positively charged particles in atoms of a given element is equal to the number of protons in the nucleus of the atom. This number is referred to as the atomic number of the element and it determines the element's identity on the periodic table.


Which number associated with an atom is a characteristic property?

Atomic number is a characteristic property of an atom. Each element has its own unique atomic number, which is the number of protons in the nucleus of an atom.
