How can you tell two atoms apart?
Atoms can be distinguished by the number of protons in their nucleus, known as the atomic number. Atoms of different elements have a unique number of protons, which determines their identity on the periodic table. Additionally, atoms can also be differentiated by their electron configuration and isotopic composition.
How many atoms are there in a mole?
The number of atoms in one mole of atoms is known as Avogadro's Number (in honor of the scientist who first did this calculation) and it is approximately 6.02 x 10^23.Answer:Avogadro's number may be applied to both atoms and molecules. Mon-atomic elements (iron, sulfur, etc.) contain one Avogadro's Number of atoms per mole. If the substance is a compound (H2, ethane, sodium chloride, etc.) the number of molecules is equivalent to Avogadro's number, but the total number of atoms in the mole is equal to that number times the atoms in each molecule.
How many atoms are there in 1 mole of O?
There are 6.022 x 10^23 atoms in one mole of oxygen (O). This number is known as Avogadro's number.
What is the substance in which one or more atoms have the same number of protrons?
The substance in which one or more atoms have the same number of protons is called an element. Each element is defined by its unique number of protons, known as the atomic number. For example, all carbon atoms have six protons, categorizing them as carbon. Elements can exist as single atoms or as molecules consisting of two or more atoms of the same or different elements.
What is the key difference that causes atoms of one element to differ from the other atoms of all other elements?
The key difference that causes atoms of one element to differ from all other elements is the number of protons in their nucleus. This number, known as the atomic number, determines the element's specific properties.
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.
What are atoms element that have a different number of neutrons known as?
Isotopes
Atoms of the same elements that differ only in the number of neutrons are known as?
Atoms of the same element that have different numbers of neutrons are called isotopes. An isotope is known by its mass number, which is the sum of the protons and neutrons in its nucleus.

What are atoms that are of the same element having same number of protons but different number of neutrons known as?
isotopes
The measure of the number of atoms in one element that will combine with an atom of another element is?
This measure is known as the valency of an element. Valency indicates the number of hydrogen atoms that an atom of an element can combine with or displace in a chemical compound. It helps determine how elements will bond with each other to form molecules.

Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that .?
It is now known that atoms can be divided into subatomic particles (protons, neutrons, electrons) and that isotopes of an element can have different numbers of neutrons. Atoms are not indivisible and they can differ in properties even within the same element.
How many atoms in 1 mole?
There are 6.02 x 10 ^ 23 atoms or molecules of a substance in one mole of that substance. This is Avogadro's number.
A is substance in which one or more atoms have the same number of protons?
An element is a substance in which all atoms have the same number of protons. Each element is identified by its unique number of protons, known as the atomic number.
If you have a mole of sulfur how many sulfur atoms do you have?
A mole of sulfur contains 6.022 x 10^23 sulfur atoms. This number is known as Avogadro's number and represents the number of atoms or molecules in one mole of a substance.
How many atoms are there in 1 mol of an element?
There are approximately 6.022 x 10^23 atoms in 1 mol of an element, which is known as Avogadro's number. This number is a constant and represents the number of atoms, ions, or molecules in one mole of a substance.
