Element 19, potassium: atomic radius = 227 pm.
Element 35, bromine: atomic radius = 120 pm.
There are 19 atoms in one molecule of ammonium nitrate: 2 nitrogen atoms, 4 oxygen atoms, and 9 hydrogen atoms.
There are four elements, vix. Carbon,(C) , Hydrogen(H), Nitrogen (N) and Oxygren (O). There eight(8) x carbon nine (9) by hydrogen one (1) by nitrogen two (2) by oxygen . Total number of atoms is 8+9+1+2 = 20 The answer!!!!
It's difficult to give an exact number, but a pinhead that is 1 mm wide could contain roughly 10^17 to 10^19 atoms. This estimate is based on the size of a typical pinhead and the size of an average atom.
Elements are composed of atoms, which are made up of protons, neutrons, and electrons. Protons and neutrons make up the nucleus of an atom, while electrons orbit around the nucleus. The specific number of protons in the nucleus determines the element's identity on the periodic table.
In 3H3PO4, there are 3 hydrogen atoms, 3 phosphorus atoms, 12 oxygen atoms, and 4 additional hydrogen atoms for a total of 19 atoms.
There are 19 atoms in one molecule of ammonium nitrate: 2 nitrogen atoms, 4 oxygen atoms, and 9 hydrogen atoms.
Oxygen-18, fluorine-19 and neon-20 atoms have 10 neutrons each.

Potassium is NOT a compound made of 2 elements,it is an elementby itself, exsisting of one kind of atoms: symbol K, group 1atomic number 19, mass 39.1 a.m.u.

Using that unit of measure, about 1 to 2 x 10e-19 terametres. It's probably a good idea to use a smaller unit of measure than terametres to measure atoms.
5.3×10^19 atoms
Sample size: 5 Sum of sample elements: 94 Mean: 94/5 = 18.8
