Francium has one valence electron, its atomic no is 87 and it belong to Ist group of Periodic Table.
Francium is in group I, the alkali metal group, so it has one (1) valence electron.
Fr --> Fr+ + e-
Only one valence electron
Francium has seven valence shells.
Francium has 7 electron shells.
Francium has 7 electron shells.
francium only has one valence electron (one electron in the outermost shell).
There are 2 electrons in valence shell of calcium. :-)
there are 36 electrons in a valence shell. -cmoney
Valence electrons are the total amount of electrons on the outermost shell of an atom. Meaning if the last shell has two, the valence electrons are two. But a complete valence shell would hold eight.
it needs six more electrons to have a full outer valence shell.

A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
Valence electrons are placed in the outermost shell of electrons.

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.
