Component having Smallest Atomic Size is 'Helium' having range approx. 31pm
I have seen that numerous individuals are noting with respect to hydrogen Atom however the genuine reason is along a period (left to right) the nuclear number increments while the valence electrons stay in a similar shell. Along these lines because of the expanding atomic charge (pulling electrons closer to the core) the radii of the iotas decline left to right.
Furthermore, as should be obvious from the table, Hydrogen and Helium are in a similar period so Helium having littlest size

I had the same question and somehow got it right :)
In order to <span>complete and balance the following reactions, you should add a Fe into it. So it will look like uo2+ +cr o^2- 7 ـــــــــــــــــــــ uo2+ +cr3+Fe. The answer to the following given statement or missing answer is Fe. </span>
Answer:
1=100 1 Kilogram (kg) is equal to 100 dekagrams (dag). To convert kilograms to dekagrams, multiply the kilogram value by 100.
Explanation:
<h3>
Answer:</h3>
Atoms of elements on the reactants side
- 2 Carbon atoms
- 6 Hydrogen atoms
- 7 Oxygen atoms
<h3>
Explanation:</h3>
- The equation; C₂H₅OH+ 3O₂ →2CO₂+ 3H₂O is balanced.
- A balanced chemical equation has an equal number of atoms of each element on either side of the equation.
- For example, in the equation given, the number of atoms of each element is equal on both sides of the equation.
- There are 2 carbon atoms, 6 hydrogen atoms, and 7 hydrogen atoms on either side of the equation.
- According to the law of conservation of mass, the mass of the reactants should be equal to the mass of reactants.
- Therefore, chemical equations are balanced for them to obey the law of conservation of mass.
