what is the electronic configuration of Li, O, F, P, and B.
Please help!!!!
To find the electronic configuration of an element, you can use the periodic table.
For Lithium (Li):
1) Locate lithium on the periodic table, which is in the second row and belongs to group 1.
2) The atomic number of lithium is 3, meaning there are 3 electrons.
3) The electronic configuration of lithium is 1s² 2s¹.
For Oxygen (O):
1) Find oxygen on the periodic table, which is in the second row and belongs to group 16.
2) The atomic number of oxygen is 8, meaning there are 8 electrons.
3) The electronic configuration of oxygen is 1s² 2s² 2p⁴.
For Fluorine (F):
1) Locate fluorine on the periodic table, which is in the second row and belongs to group 17.
2) The atomic number of fluorine is 9, meaning there are 9 electrons.
3) The electronic configuration of fluorine is 1s² 2s² 2p⁵.
For Phosphorus (P):
1) Find phosphorus on the periodic table, which is in the third row and belongs to group 15.
2) The atomic number of phosphorus is 15, meaning there are 15 electrons.
3) The electronic configuration of phosphorus is 1s² 2s² 2p⁶ 3s² 3p³.
For Boron (B):
1) Locate boron on the periodic table, which is in the second row and belongs to group 13.
2) The atomic number of boron is 5, meaning there are 5 electrons.
3) The electronic configuration of boron is 1s² 2s² 2p¹.
I hope this helps! Let me know if you have any more questions.
