Question

$\large \textbf {Question:-}$

$\textbf {Charges \:on\: elements\: from\: 1\: to\: 30\:}$

Answer 1

Few Points to remember before knowing the charges attained by the respected elements :-

• Those elements which accepts electron for gaining stability are abbreviated  with negative(-)  sign .
• whereas, the elements which donates electron for gaining stability are abbreviated with positive(+) sign.

so here we go with your answer !

1. H (Hydrogen) = +1
2. He (Helium) = 0
3. Li (Lithium) = +1
4. Be (Beryllium)= +2
5. B (Boron)= +3
6. Carbon (Carbon)= 0
7. N (Nitrogen) = -3
8. O (Oxygen) = -2
9. F (Fluorine) = -1
10. Ne (Neon) = 0
11. Na (Sodium) = +1
12. Mg (Magnesium) = +2
13. Al (Aluminum)  = +3
14. Si (Silicon) = 0
15. P (Phosphorous) = -3
16. S (Sulphur) = -2
17. Cl (Chlorine)  = -1
18. Ar (Argon) = 0
19. K (Potassium) = +1
20. Ca (Calcium) =  +2
21. Sc (scandium)  = +3
22. Ti (Titanium) = +2, +3 , +4
23. V (Vanadium) = +2, +3 , +4
24. Cr (Chromium) = +2, +3 , +6
25. Mn (Manganese) = +2 , +3 , +4
26. Fe (Iron) = +2, +3
27. Co (Cobalt) = +2, +3
28. Ni (Nickel) = +2, +3
29. Cu (copper) = +1, +2
30. Zn (Zinc) = +2

Please Note :- charges varies when elements are in different states (few)

Answer 2

Answer :

Now we are starting with a small thing that is gaining and losing of electrons.

So , here we are using two terms electropositive elements and electronegative elements.

What is this ?

Electropositive are those who are losing there electrons to form a ion but on another hand electronegative are gaining electrons to form ions .

Some of them are forming covalent bonds those who share there electrons like hydrogen and carbon these two elements are forming very strong covalent bonds.

In the last shell of carbon there are 4 valence electrons but carbon neither gain or lose there electrons because it's need high energy and these are near to nucleus or in "2" orbit also hydrogen have single valence electron so it neither lose their electron it's only share it.

Now we are going to start charges on elements 1 - 20 and then 20 - 30

Zero means inert gases or elements ( neither form ions )

01 Hydrogen( +1 )

02 Helium ( Inert gas 0 )

03 Lithium ( +1 )

04 Beryllium ( +2)

05 Boron (+3)

06 Carbon ( Covalent bond 4+ , 4- )

07 Nitrogen ( -3 )

08 Oxygen ( -2 )

09 Flourine ( -1 )

10 Neon ( Inert gas 0 )

11 Sodium ( +1 )

12 Magnesium ( +2 )

13 Aluminium ( +3 )

14 Silicon ( Covalent bond 4+ , 4- )

15 Phosphorus ( -3 )

16 Sulphur ( -2)

17 Chlorine ( -1 )

18 Argon ( Inert gas 0 )

19 Potassium ( +1 )

20 Calcium ( +2)

Here the valence electrons are two far from the nucleus of an atom so it's easier to lose the electrons as compare to the elements in b/w 1 -18 .

In higher classes you learn about it in details.

Transition Elements(Metal's)

21 Scandium ( +3 )

22 Titanium ( +2 , +3 , +4 )

23 Vanadium (+2 , +3 , )

24 Chromium ( +2 , +3 )

25 Manganese ( +2 , +4 )

26 Iron ( +2 , +3 , +4 )

27 Nickel ( +2 , +3 )

28 Cobalt ( +1 , +2 )

29 Copper ( +1 , +3 )

30 Zinc ( +2 )
