The first person to recognize the total ratio of the number atoms is the same as the total ratio of the ratio of the mass is JOHN DALTON.

  • This is also called the "Law of Multiple Proportion"

Do atoms have the same properties as an element?

No, atoms are the smallest units of matter that retain the properties of an element. The properties of an element are determined by the number of protons in its nucleus, which defines its atomic number and unique characteristics. When atoms combine to form molecules, the properties may change due to new interactions.


What is the name for atoms of an element that have different masses?

An atom or element that have different masses are known as isotopes.


Why don't equal masses of carbon and oxygen contain the same number of atoms?

The atoms are different sizes.


What are atoms of the same element but with different masses?

Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.


What is the maximum number of sulfur atoms you can combine with a carbon atom?

Atoms having the same atomic number but different atomic masses?

Isotopes


What are atoms that have different masses but the number of protons?

Atoms that have different masses but the same number of protons are called isotopes. Isotopes of an element have the same number of protons, which determines the element's identity, but a different number of neutrons, leading to variations in atomic mass.


What are different atoms of the same element that have different atomic masses?

These atoms are called isotopes and they have a different number of neutrons.


What is the known as valency?

It is combining capacity of an atom of an element and is numerically equal to the number of hydrogen atoms or number of chlorine atoms or double the number of oxygen atoms with which one atom of the element can combine.


Atoms of different elements combine in whole number what?

That is the law of constant composition.


Are needed for atoms to combine?

Bonds are needed in order for atoms to combine
