1 electron in the s orbital
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
An elements period is determined by the number of electrons it has in its outer shell.
Rubidium is silvery metal with a valence electron in its outer shell. It conducts electricity.
1 electron in the s orbital
1 electron in the s orbital
alkali metal
The electron outside the shell donate its electron to the one inside the shell
Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells

The element with 55 electrons is Caesium (Cs). Caesium is an Alkali Metal in Period 6 of the Periodic Table. It has the atomic number 55. It has 55 electrons in 6 shells with 1 electron in the outer shell.
Because an electric current is basically electrons moving along, so if there are more slightly freer electrons there wil be a greater facility for electron movement.
I assume you are talking about the Alkali metal group which in fact would readily loose their outer electron to form a 1+ cation (have a full valence electron shell).
The element with atomic number 45 is Rhodium (Rh). Rhodium is a transition metal in Group 9, Period 5 of the Periodic Table. Rhodium has 45 electrons in 5 electron shells with 1 electron in the outer shell.
