Most of them are 5 billion years old or older. They were formed in stars by thermonuclear fusion. When those stars became novae or supernovae, the atoms were blasted out into space. Some of these would have formed the stellar nebula from which our solar system condensed. Since the sun is around 4.5 billion years old, these atoms, which must have become part of the solar nebula before that, must be older than 4.5 billion years.
No, that is just plain old covalently bonded sulfur dioxide.
When new bonds are formed between atoms, energy is released and this process is known as exothermic process. Similarly when old bonds break, energy from the surrounding is absorbed and is known as endothermic process.
Fe3O4 has a total of 7 atoms, with 3 iron atoms (Fe) and 4 oxygen atoms (O).
They have to rely on indirect substances because of Ernust Rutherford's experiment. He was a british when he was about 28 years old. He almost died in world war 2. His really name was Sgt. Ernust Jefferey. But when he became old, he changed his name and became a scientsist.
There are a total of 13 atoms in 3CaCl2: 3 calcium atoms and 6 chlorine atoms.
when atoms break their old links and form new links with other atoms it is called chemical reaction
The age of atoms is the size of your penis calculated in meters
when atoms break their old links and form new links with other atoms it is called chemical reaction
2500
5000 years old
After 10740 years, half of the sample would have decayed, so there would be 200 atoms left. If the original sample had 400 atoms, then there would be 200 atoms left in the sample after 10740 years.
They are about as old as the universe. In other word they are over 13 billion years old.
No, that is just plain old covalently bonded sulfur dioxide.
The atoms might vary slightly, they come from the remains of exploded stars that created them in nuclear fusion but the stuff that makes up atoms has been around since just after the big bang. Hydrogen would be the oldest atom in our bodies. A lot of lighter atoms were created while stars were still alive, heavier ones are created when they explode (need way more heat/energy to fuse).
There are 20 atoms and there are 6 Carbon atoms, 8 Hydrogen atoms, 6 Oxygen atoms.
there is no relationship of what atoms mix with what atoms
Atoms have the highest energy at the transition state of a reaction, also known as the activated complex. This is when the reactants have absorbed enough energy to break old bonds and start forming new ones.
