I need help naming these elements....??

Question

These r the electron configurations:
Also, if you know them, i need the symbold with the elements too.
A) 1s2 2s2 2p6 3s1
B) 1s2 2s2 2p3
C) 1s2 2s2 2p6 3s2 3p2
D) 1s2 2s2 2p4
E) 1s2 2s2 2p6 3s2 3p6 4s1
F) 1s2 2s2 2p6 3s2 3p6 3d2 4s2
PLEASE HELP ME!!!
thank u for your time if you answer these questions

Answer 1

The Answers r as follows:

1s2 2s2 2p6 3s1 is Sodium. The symbol of Sodium is Na.
1s2 2s2 2p3 is Nitrogen. It's symbol is N
1s2 2s2 2p6 3s2 3p2 is Silicon. It's symbol is Si.
1s2 2s2 2p4 is Oxygen. It's symbol is O.
1s2 2s2 2p6 3s2 3p6 4s1 is Potassium. It's symbol is K.
1s2 2s2 2p6 3s2 3p6 3d2 4s2 is Titanium. It's symbol is Ti.

Answer 2

Here's a method in doing this.Since there are all specified as elements, just count the total number of electrons and match it with the atomic number in the periodic table

i.e. 1) total number of electrons=2+2+6+1=11 (sodium)

Answer 3

You can just add the numders after the letters (S,P and D orbitlas) which indecates the number of electrons filling the orbitals and the sum will show the number of total electrons. Then you can look in the periodic table and look for the number above the element. But I'll give the answers anyway:
A)sodium________Na
B)nitrogen________N
c)silicon_________Si
D)oxygen________O
E)potassium_______K
F)titanium_______Ti

good luck...

Answer 4

Review your text. These tell you how many electrons are in each orbital and which orbital they are inl. total up the number of electrons. in A) you have 11 electrons so it is atomic #11 = Na (sodium) You do the rest.

Answer 5

a) sodium
b) nitrogen
c) silicon
d) Oxygen
e) pottasium
f) Chromium
