Hola!
→ Your query:
Atoms of one element easily changes to atoms of another element. Is it True? or False?
→ The answer is: TRUE
→ Reason :
We can change atom of one element to other atom by adding more particles into them. ex : Neutron, Protons and Electrons.
This is how nuclear fusion works.
hope it helps!
Nitrogen has one single bond, one double bond, no triple bonds, one unshared pair of electrons.
Answer:
Number of atoms =1.806×10²⁴
Explanation:
You have the number of moles of Carbon tetrachloride which is n=3
And you are looking for number of atoms that are in the sample, which are represented by the letter "N"
The formula that has both number of moles(n) and number of atoms(N) is written as n=N/Na
Na is called the Avogadros number and it is equal to 6.08×10²³, it never changes(it is a constant)
So you will substitute the number of moles and the avogadros number to you formula, and the only unknown will be the number of atoms which you are looking for
- n=N/Na
- 3=N(6.02×10²³)
- N=1.806×10²⁴ atoms of CCl
NB: N does not represent the number of atoms only. It may also represent the number of particles or molecules...
