Radiometric Dating. It's used to find the dates of ricks and other objects based on what the known decay rate of radioactive isotopes. Different forms of this method can also estimate the age of natural and man-made materials.
A visual representation of covalent bonding which represents the valence shell electrons in the molecule is said to be a Lewis structure. The lines represents the shared electron pairs and dots represents the electrons that are not involved in the bonding i.e lone pairs.
Number of valence electrons in each atom:
For Carbon,
= 4
For Hydrogen,
= 1
For Nitrogen,
= 5
The Lewis structure of
is shown in the attached image.
The formula of calculating formula charge =
-(1)
where, F.C is formal charge, V.E is number of valence electrons, N.E is number of non-bonding electrons and B.E is number of bonding electrons.
Now, calculating the formal charge:
For

The formula charge of each atom other than hydrogen is shown in the attached image.
The first one is exothermic because energy is a reactant, the second formula is endothermic
Answer:
The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator. The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collectors
Answer:
carbon
Explanation:
Atomic radius represents the distance from the nucleus to the outer shell of an element.
