How many valence electrons are in rubidium?
In common with all the other Alkali Metals, Rubidium has one valence electron.
How many electrons does Cesium have in its outer energy level?
Cesium, or Cs, has 1 valence electron.
Which element has 19 protons and 1 valence electron?
Potassium has 19 total electrons and one electron in its 4th energy level.
Which electron that would emit the greatest amount of energy by dropping electron levels?
N=2 To N=1 The greatest energy change comes between the lower energy levels.
How many energy levels in a astatine?
Six electron shells
How many electron levels does sodium 23 have?

What is hydrogen outermost energy level?
If you are referring to the valence shell; the answer is one.
How many energy levels are in an electrically neutral sodium atom?
the element sodium has 1,000,000 million energy levels.
How does the number of electrons in outer energy levels relate to the position of an element in the periodic table?
the group number shows the number of electrons in the outermost energy levels. forexample sodium (Na) have 1 electron in the outermost shell and is placed in the group 1. Elements are grouped in rows depending on their energy levels, or valence electron numbers. Columns of elements are those that are chemically similar, or react
How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
What is the valence of potassium?
1 valence electron
The outer electron levels of hydrogen?
Hydrogen has only 1 electron and has only 1 energy level.
How many valence electrons are in rubidium?
In common with all the other Alkali Metals, Rubidium has one valence electron.
How many valence electrons does the element cesium have?
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
How many valance electrons does hydrogen have?
Hydrogen has only one electron. Just the one. And it is a valence electron.
How many electrons does Cesium have in its outer energy level?
Cesium, or Cs, has 1 valence electron.
