They really didn't they thought of a theory of everything being made up of atoms. Such as Mendeleev and Mosley
yes
Atoms are important because they make up everything in existence. Every object you can find will be made of atoms.
.1146g of mass of Unknown and 12.00ml of NaOH. Find the moles of acidic H atoms
Atoms are in every solid object but you cannot see them as they are so small.
In a lump of iron, you would find iron atoms. Iron is a pure element composed solely of iron atoms, with each atom containing 26 protons and typically 26 neutrons in its nucleus.
Neutrons are found in the center of atoms.
thats what i wanna find out
To find the number of atoms in 0.575 grams of cesium, you first need to convert grams to moles using the molar mass of cesium. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in one mole of cesium. Multiply the number of moles by Avogadro's number to find the number of atoms in 0.575 grams of cesium.
You find the neutrons with the protons, inside the nucleus.Most neutrons are in the nucleus of atoms.
18 carbon atoms (6 in each)
An atom-gram of any element contain 6,022 840 57.10e+23 atoms.
