An isotope is defined as:
Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative Atomic Mass but not in chemical properties; in particular, a radioactive form of an element
So basically, an isotope is from the same place (element) and has the same number of protons, but the number of electrons differ.
So isotopes are not subatomic; the protons and electrons that make an isotope are subatomic.

What subatomic particle contributes alomst no weight to an atom?
The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.
How did subatomic particles and isotopes affect the atomic theory?
The discovery of these left his atomic theory (which states that atoms are indivisible, singular and the same respectively to elements) riddled with wholes.
What subatomic particles make up the atom?
protons, neutrons and electrons are the main subatomic particles of the atom. There are the same number of protons as electrons, which is equal to the atomic number. The number of neutrons may vary according to the isotope of the element.
What subatomic particle determines if an element is an isotope or not?
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
Which statement about subatomic particles is not true?
Subatomic particles are the same size as basketballs.
How do isotopes of the same element differ with regards to subatomic particles?
Same number of protons; different number of neutrons. The number of electrons will also be the same, assuming a neutral atom.
What subatomic particles can differ between neutral atoms of the same element?
The subatomic particle that makes atoms of different elements different from each other is the proton. This is given as the atomic number of the element on the periodic table.
What particles differ in number in isotopes of the same element?
neutron
Name the subatomic particles that the number of this particle is always the same as the atomic number?
The proton
What 2 subatomic particles can you determine from the atomic number?
Atomic number is same as the number of protons and number of electrons.
What subatomic particle contributes alomst no weight to an atom?
The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.
What two subatomic particles are the same in number in any stable element?
Protons and electrons
What aspect of an atom's subatomic particles defines which element it is?
The number of protons determines the element, and is the same as its atomic number.
How did subatomic particles and isotopes affect the atomic theory?
The discovery of these left his atomic theory (which states that atoms are indivisible, singular and the same respectively to elements) riddled with wholes.
What subatomic particles make up the atom?
protons, neutrons and electrons are the main subatomic particles of the atom. There are the same number of protons as electrons, which is equal to the atomic number. The number of neutrons may vary according to the isotope of the element.
What subatomic particles contribute to the mass of?
The atomic mass is the sum of the number of protons and the number of neutrons found in each atom of that element (electrons do not contribute). They are sometimes seen on periodic tables to have a decimal in the atomic number, this is for elements with more than one common isotope (an isotope of an element is the same number of protons but with a different number of neutrons), in which case an average of the common isotopes can be used.
What subatomic particle determines if an element is an isotope or not?
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
