Explanation: • Electronegativity is the tendency of an atom to attract the electrons in a bond towards it. • Ionization energy is the energy that should be given to a neutral atom to remove an electron from it. The difference in the electronegativity between the two elements is quite small, but the main reason for it is because chlorine is one period below oxygen. Chlorine’s valence electrons are thus less tightly bound than those of oxygen, so they would have lower first ionization energy. Does sodium or potassium have larger ionization energy?
1:electron pair geometry->trigonal pyramid
2: molecular pair geometry->linear
Answer:
0.00172 M
Explanation:
According to the Lambert's Beer law:-
Where, A is the absorbance
l is the path length
is the molar absorptivity
c is the concentration.
If a graph is plotted between the concentration and absorbance, then the slope is:- 
. So,
<u>0.00172 is the molar concentration of 
in the unknown solution.</u>

Explanation:
<h3> 1 All the matter is a atom. atom can not Be destrued </h3><h3>2All atom of given element are identify in mass and properties</h3><h3>3 A chemical reaction is rearranged of atom</h3>
Answer:-
Carbon cannot reduce sodium, magnesium and calcium to their respective metals because carbon is lower than them in the electrochemical series.
Only metals higher in the electrochemical series can displace metals placed lower.
Sodium, magnesium and calcium are obtained from their salts by electrolysis of the salts.
Sodium Chloride is the sodium salt used. Sodium is deposited at cathode.
Chlorine gas is produced from the process.
Cathode: 2Na+ + 2e- --> 2Na (Reduction)
Anode: 2Cl- --> Cl2 + 2e- (Oxidation)
Potassium and Calcium are two other metals that can be extracted by the same method
