there are 90 different naturally occurring types of atoms,also there are scientists in labs who have made around 25 more.

Atoms of different elements are different because they have different numbers of what type of particle?
Atoms are considered to be of the same element if they have the same number of protons. If their atoms have a different number of NEUTRONS, they are known as ISOTOPES of the same element.
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.
Atoms of the same element that differ in the number of neutrons they contain are known as?
they are known as isotopes. Dont ask people to do your homework
Atoms chemically bonded with other atoms are known as what?
Ions
How do you find the largest atom or ion in a set?
It may be decided if atomic number and period of atoms in periodic table are known.
What is the density of Ununbium?
Impossible to be measured with a number of atoms obtained under 1oo.
Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that .?
Atoms are divisible.
The measure of the number of atoms in one element that will combine with an atom of another element is?
These atoms are known as valence atoms.
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
What are Atoms that vary in the number of neutrons found in their nuclei called?
Different elements with same number of neutrons are known as isotones.
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.
How many atoms of phosphorus are present in a molecule of phosphorus?
Today are known the phosphorus molecules P2 and P4.
What are atoms that are of the same element having same number of protons but different number of neutrons known as?
isotopes
What are element that differ in the number of neutrons known as?
Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.
Atoms of different elements are different because they have different numbers of what type of particle?
Atoms are considered to be of the same element if they have the same number of protons. If their atoms have a different number of NEUTRONS, they are known as ISOTOPES of the same element.
If there is more than one atom of a particular element the number of atoms is written using a small number known as a?
Compound
