Romashka [77]
9,353 - 1,095 - 5,217 = mN
3,041 = mN

H:C:N= 1,095/1 : 5,217/12 : 3,041/14
H:C:N = 1,095 : 0,43475 : 0,2172
H:C:N = 5,037 : 1,99985 : 0,99912 ≈ 5 : 2 : 1

How small atom partical are?​
ElenaW [278]

Atoms of particles are so small that they cannot be divided further by any physical means.

<h3>What are atoms?</h3>

According to John Dalton, atoms are the smallest, indivisible particles of elements.

However, it was later found out that chemically, atoms consist of protons, neutrons, and electrons.

Thus, the indivisibility of atoms that John Dalton was referring to must be that of physical division.

In other words, the particles of atoms are so small that dividing them further using physical means is absolutely impossible.
