ElementAtomic numberElectron configurationhydrogen11s1helium21s2lithium31s22s1beryllium41s22s2How do you write the electron configuration?
Writing Electron Configurations. When writing an electron configuration, first write the energy level (the period), then the subshell to be filled and the superscript, which is the number of electrons in that subshell. The total number of electrons is the atomic number, Z.

How are 15 electrons arranged in a phosphorus atom?
A neutral phosphorus atom has 15 electrons. Two electrons can go into the 1s subshell, 2 can go into the 2s subshell, and 6 can go into the 2p subshell. That leaves 5 electrons. Of those 5 electrons, 2 can go into the 3s subshell, and the remaining 3 electrons can go into the 3p subshell.
Where is 5f on the periodic table?
In order to make the overall shape of the table more compact and convenient to display, scientists have adopted the convention of removing the elements with atomic number 57 through 70 and 89 through 102 (the latter being the 5f portion of the table) from their natural position between the s and d blocks and placing …

What does the symbol 39 19 K mean?
It is the number under the element symbol. For potassium it is about 39. This means that the atomic weight is 39 for both protons and neutrons. Since we know that the number of protons is 19 we can calculate the number of neutrons (39 19) as 20.

How do you find the bond order?
- Draw the Lewis structure.
- Count the total number of bonds.
- Count the number of bond groups between individual atoms.
- Divide the number of bonds between atoms by the total number of bond groups in the molecule.
