This is a tricky question because of the way it is phrased. Atoms are the most fundamental unit of stable matter and are composed of varying amounts of protons, neutrons and electrons. In neutral atoms, there are as many positively-charged protons in the nucleus as there are negatively-charged electrons. An imbalance between the number of protons and electrons results in a charged ion. The charge is determined by how many more protons (for positively-charged cations) there are than electrons or for how many more electrons (for negatively-charged anions) there are than protons. Neutrons, found in the atom's nucleus, are present in equal or greater quantity than are protons but the relationship between their number and the number of protons is not fixed. The identity of the atom (hydrogen vs. chlorine vs. carbon, etc...) is determined solely by the number of protons present in the nucleus.
From all this can you answer your question?
Proton Number
A specific number of either protons or electrons is a characteristic of atoms of a particular element.
The gas has molecules that are single atoms, as do the noble gases.
all atoms with an atomic number under 40
The formula of this compound would be FeS2 , this is iron pyrites. Often called fools gold.
the number of atoms in a certain space its really of any significance , u can do all the everythong without it
As in number? No of atoms = avagadros number (6.02X10^23) times number of mole of atoms
To calculate the number of moles from the number of atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Divide the number of atoms by Avogadro's number to find the number of moles.
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction, only rearranged. This means that the number of calcium atoms present before the reaction must be the same as the number of calcium atoms present after the reaction. Therefore, if a certain number of calcium atoms react to produce more calcium, the total number of calcium atoms will remain the same.
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
The identity of every element is given by the number of protons in the nucleus. To keep electrical neutrality, they also have the same number of electrons.See the Related Questions for more information about protons, neutrons, and electrons in atoms.
