What else can I help you with?
What geological material consists of a certain number of atoms and exactly twice the number of sulfur atoms?
The formula of this compound would be FeS2 , this is iron pyrites. Often called fools gold.
What are atoms that are exactly the same called?
Element
Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
What are atoms of an element that have the same number of protons as other atoms of that element but a different number of neutrons called?
They are called isotopes,
What Atomic particle controls its reactivity?
The number of protons in the nucleus will ALWAYS be the same for a specific element.(ex: Hydrogen always has EXACTLY 1 proton)But, the number of electons and neutrons can vary in a particular element.
How many carbon atoms are present in a mole of carbon12?
6.023 x 1023

What are atoms that are exactly the same called?
Element
All Atoms Of An Element Are Exactly?
All atoms of the same element are not identical. The atoms of same element with different number of neutrons are called as isotopes. Although, the number of protons and electrons are same in every atom.
Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
What are atoms of an element that have the same number of protons as other atoms of that element but a different number of neutrons called?
They are called isotopes,
What is the most appropriate to express number of molecules per volume?
Avogadro's number is the number of molecules in a mole of a substance. This is expressed as 6.022 141 29 E23 /mol. This is defined as the number of atoms in 12 grams of carbon12. A mole of any gas has this number of molecules. Any fraction of that mole must be divided into the number.
What are the atoms that have the same number of protons called?
Two atoms that have the same number of protons are called isotopes.
What are two atoms that the same number of proton called?
Two atoms that have the same number of protons are called isotopes.
What are the two atoms that have the same number of protons called?
Two atoms that have the same number of protons are called isotopes.
Atoms of the same atomic are called what?
isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons
What Atomic particle controls its reactivity?
The number of protons in the nucleus will ALWAYS be the same for a specific element.(ex: Hydrogen always has EXACTLY 1 proton)But, the number of electons and neutrons can vary in a particular element.
