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.

It is generally thought that the higher elements (those elements with a nucleus more than just a single proton) were created later via nuclear fusion in the cores of stars, As is still happening in the sun right now. And get distributed into space rubble (like the Earth) via stellar explosions.

When atoms combine with or break apart from other atoms a what occurs?
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.
How many atoms in CBr4?
It is 1 calcium atom and 2 bromine atoms which totals 3 atoms
How many atoms are in magnesium?
how many atoms are there in magnesiumoxide 2 atoms are in magnesium 2 atoms are in magnesium
Why do atoms tend to be bonded to other atoms'?
The correct answer is: Atoms are often more stable when bonded to other atoms
How many atoms does Fe3O4 have?
3 Fe atoms plus 4 O atoms totals 7 atoms.
When atoms break their old links and form new links with other atoms what has occurred?
when atoms break their old links and form new links with other atoms it is called chemical reaction
How old are the atoms that make up the body of an 18-year-old student?
The age of atoms is the size of your penis calculated in meters
If a sample is 10740 years old and has 400 atoms how many atoms are there after the organisms died?
1,600
What is it called when atoms break old links and form new ones with other atoms?
when atoms break their old links and form new links with other atoms it is called chemical reaction
How old is the idea that matter is composed of atoms?
2500
A specimen is found to have 3 atoms of a radioactive isotope for every 9 atoms of the stable decay product The radioactive material has a half-life of 2500 years how old is the specimen?
5000 years old
How old are the Hydrogen atoms that make up 63 percent of your body mass?
They are about as old as the universe. In other word they are over 13 billion years old.
Explain chemical changes in terms of the structure and motion of atoms and molecules?
a chemical change destroys the old atoms and molecules to make completely new ones and a completely new substance.
How old are the oldest atoms that make up a 15 year old person?
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).
Is there a relationship of what atoms mix with what atoms?
there is no relationship of what atoms mix with what atoms
How many many atoms and what kinds of atoms are in C6H8O6?
There are 20 atoms and there are 6 Carbon atoms, 8 Hydrogen atoms, 6 Oxygen atoms.
A rock originally had 1500 atoms of U-235 and it now has 750 how old is it?
For a rock to have started with 1500 atoms of any element and now have 750 it has undergone radioactive decay equal to one full half life (i.e. there are half the number of atoms now than at the beginning).Uranium-235 has a half life of 7.038×108 years.As such, the rock is 7.038×108 or 703 million years old.
