'''Ca'''<br />
('''ال|,^,~,etc. تعني عناصر المجموعات المختلفة التي يتم تقسيمهاB,C,N,O,F are one group.''')
'''Consider the first group. H,He,Li,Be. Remember as it is. It's a nice ring to it which helps. One advise is remember it as the Full forms. Hydrogen, Helium, Lithium and Beryllium. End with -ium'''<
▲'''Consider the first group. H,He,Li,Be. Remember as it is. It's a nice ring to it which helps. One advise is remember it as the Full forms. Hydrogen, Helium, Lithium and Beryllium. End with -ium'''</br>
'''Next group is B,C,N,O,F. All these are single letters. REMEMBER THEM LIKE A RUSSIAN NAME, BCNOF or remember it using the short forms because in this group all are alphabets not a combination like Be or Cl.'''<br />
'''Next group is Ne,Na. Okay try reading it together. Sounds like Nina(NeNa) right?. So that's how you remember it'''<br />
السطر 242 ⟵ 241:
'''Next group is Si,P,S. We can make a proper word out of this. Sips(Si,P,S).'''<br />
'''Next group is Cl,Ar,K. Make a word out of this. Clark(Cl,Ar,K).'''<br />
'''And finally. Remember Ca as it is'''
<br />
'''The first 20 elements is very much required to do good in chemistry.'''
'''The order mentioned above is the ascending order of atomic number of elements'''
<br />
<br />
'''So it is:'''<br />
'''The ring, BCNOF, Nina(NeNa), Migal(Mg,Al), Sips(Si,P,S), Clark(Cl,Ar,K) and Ca'''
