Different atoms either have a different number of protons(which makes them different elements) or a different number of neutrons (which makes them isotopes of the same element).
For example, hydrogen has one proton (and usually no neutrons) while helium has two protons (and usually two neutrons). However, hydrogen with one proton and two neutrons is called tritium(3H) while helium with two protons and one neutron is called helium-3 (3He).

Secondarily in the number of neutrons in the atoms nucleus (for isotopes).
Also it is the "surface" of the atom that gives it is unique chemical properties. The protons and neutrons are deep inside the atom and it is the electrons that form the "surface". Therefore it would be true to say that it is the electrons (their number and which electron shells are filled) that give atoms their properties and make one element different from another.

∙ 12y agoThe core of an atom is comprised of neutrons and protons. While the number neutrons in an atom may vary in an element, the number of protons must stay the same.
That means Hydrogen will always have 1 proton, helium will have 2 protons, lithium will have 3 protons, ect...
T>o sum it up: Its the number of protons in the core of an atom.

How are atoms and elements different?
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
What are elements and what make them different from one another?
Elements are pure substances that cannot be broken down by chemical means. The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
What part of an atom can move to another object?
When an atom of one element is brought in contact with an atom of another element, electrons get transferred from one element to another. However, if the atoms of same element come together then electrons are shared and not transferred. Exception to this is elements in noble gases.
What is the smallest unit of all matter that makes up an element?
An atom.
What is the difference between elements and atoms?
An atom is the smallest piece of an element. Said another way, and element is made up one and only one kind of atoms.
What makes one atom of an element different from another?
The atomic number or z number or the number of protons is what makes one atom different from another. The atomic number or z number or the number of protons is what makes one atom different from another.
What makes one elemtn different from another?
The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
What makes element different from one another?
The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
How Difference atom and element?
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
What is the element in hydrogen?
Hydrogen is an element, there will be atom that makes up an element and not element that will turn into another.
How are atoms and elements different?
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
What makes one element different from another atom based on atomic particles?
One element differs from another element by the number of protons in their atoms. The number of protons in the atom is known as the atomic number. Also one isotope of an element differs from another isotope of the same element by the number of neutrons in their atoms.
What number can be different and allow the atom to still be the same element?
the number of electrons can be different; it makes the element become an ion.
What part of an element atom makes it different from other element?
Its protons. The atom changes depending on how many protons it has. See also atomic number.
What are elements and what make them different from one another?
Elements are pure substances that cannot be broken down by chemical means. The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
What makes oxygen element different from other element?
It is the same for each and every element, it's the number of protons in the nucleus of one atom of the element.
What is amount of protons found in the nucleus of an atom?
Every different element has a different number of protons, that is what differentiates it from another element, so there is no answer to your question until you specify which atom you're talking about.
