Hydrogen- 1 electron

Helium- 2 electrons

Litium- 3 electrons

Beryllium- 4 electrons

Boron- 5 electrons

Unless ionized, the atomic number of an element will say how many protons and electrons the atom will have.

Why does the d block have only 10 elements?

The d block has only 10 elements because the d sublevel can hold a maximum of 10 electrons due to its 5 orbitals, each with a paired electron. This results in a maximum of 5 d orbitals accommodating a total of 10 electrons in the d block elements.


Which family of elements is the most unstable and why?

Group 14, or 4A. The reason for this is in all elements there are layers of electrons, the first layer is always 2 electrons, but all the layers after that have to be 8 electrons otherwise the atom is not stable, which is why elements have charges. It is all elements goal to be stable meaning having an outer layer with 8 electrons. for example, Sodium or Na has a charge of +1 because it has 11 electrons, 2 or the first layer, 8 for the next layer leaving one electron in the last layer, +1. So it is Sodium's goal to lose one electron. With group 14 the non metals have 6 and 14 electrons. if you subtract two from these (the first layer) then divide by 8 you will come up with a number ending in .5 because they have 4 electrons in their outer layer. So they're goal is too either lose or gain 4 more electrons, in anyway that is most efficient.

Which of the first 20 elements has the most unpaired electrons?

Phosphorus, which is the 15th element, has the most unpaired electrons among the first 20 elements. It has three unpaired electrons in its outer shell.


How many electrons are there in the valence shell of a nitrogen atom?

Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.
