Question

How to get the symbol of the ions for an atom only by seeing the electron numbers?
Sodium Proton Number = 23
How to get the ionic symbols for sodium only by using that information?

Answer 1

You should learn the periodic table, or atleast the first 20 elements. You can use this:

Hi Hello
Little Betty Boy Come Now Or Forever Never
Nasty Maggie Always Sings Plenty Songs Clair Aron
Kisses Cali

:D Hope that helped. Once you know those, you should be able to get the electron number. I have then in the correct periods. Remember, group 1, 1 valence electron...

Btw, Na (Sodium has 11 electrons in total, 23 is the atomic number(protons plus neutrons)

Answer 2

There is a mistake the number 23 is the atomic weight of Sodium, the atomic number is 11, that means 11 electrons and 11 protons, the electronic configuration of Sodium is 1S2S2P3S two electrons in 1s and 2s electronic levels and 6 electrons in 2P the 3S has the eleventh electron , for that sodium become an ion when he lost this electron in a reaction to form ionic bond as in NaCl .

Answer 3

I answered your other version of this question, but you'll see on the periodic table that sodium's atomic number is 11, meaning 11 protons. Add 12 neutrons and you get the atomic mass of approx. 23. The 11 protons will be balanced by 11 electrons, which proceed to a half filled outer s shell...the electronic configuration determines its place in the "period" of the periodic table.

Answer 4

Sodium has 23 protons, so it will have 23 electrons to balance. Now the first ring can hold 2 electrons, second ring can hold 8, the third ring is left with 1 electron, this lone electron can be easily displaced and if Sodium were to loss one electron it would be charged with +1.

Answer 5

You have to also know the position on the periodic table. Count spaces to the end column. There you go.

Answer 6

obviously its continuously both + 10 factors. I pour my heart out into all my solutions and that i continuously get overwhelmed to ensure somebody else get brilliant answer. yet even with this, its the feeling that you helped someone through answering their question. The gratitude. not in ordinary words that, its the positive feeling that you'll answer the question.

Answer 7

as the above guyz said, the only solution to ur problem is that u know the position of the elements in the groups/periods and their valencies .

Answer 8

It's best to memorize the periodic table. (but it's quite hard) x_x

Answer 9

don't go short cut. go periodic table and see the valancy.
