No. Not all hydrogen atoms (particles) are the same. Most do not contain any neutrons, but there are some that do contain 1 or even 2 neutrons. So, they are different.
they all take up space and all have matter, mass, and weight
Alike. They are both atomic particles with a positive charge.
A sample of water molecules is an example of a matter where all the particles (H2O molecules) are identical. Each water molecule consists of two hydrogen atoms and one oxygen atom, making them indistinguishable from one another.
pure substance
Particles in solids, liquids, and gases are alike in that they are all made up of atoms or molecules. However, the main difference lies in how closely these particles are packed together. In solids, particles are tightly packed and vibrate in place, in liquids the particles are close but can move around, and in gases, particles are spread far apart and move freely.
Hydrogen only!
No, that is just two particles of water. One particle of water has two particles of Hydrogen (and one Oxygen). What you described has 4 particles of hydrogen.
They are both small particles.
they are both made of particles
The particles of water are called molecules, composed of two hydrogen atoms and one oxygen atom.
colliods and suspentions are alike becuase both of there particles can be dispersed through the liquid
the elements in h2o are two hydrogen particles and one oxygen particles. hydrogen and oxygen are both elements.
