There is 1 valence electron. You can determine this by finding Cs on the Periodic Table. However many groups it is over from left to right is the amount of outer electrons an element has with many exceptions including transition elements

How many valence electrons are found in alkali metals Li Na K Rb Cs and Fr?
1
What element has 6 valence electrons in the 4th energy level?
This element is caesium (Cs), with the atomic number 56.
The alkali metals have how many valence electrons?
1
Is one valence electron very reactive?
If an element has one valence electron it IS very reactive. ex. Fr and Cs are extermely reactive elements.This is because the one valence electron is so far from the nucleus there is not a strong force making it stay with the element.Alkali metals
What has only one electron?
Hydrogen (H) only has one electron. If you are talking about valence electrons, all of the elements in group 1A on the periodic table have one valence electron (H, Li, Na, K, Rb, Cs and Fr).
What are the elements that have the same number of valence electrons?
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
How many electrons does Cesium have in its outer energy level?
Cesium, or Cs, has 1 valence electron.
How many electrons are in a cesium ion Cs plus?
How many valence electrons are found in alkali metals Li Na K Rb Cs and Fr?
1
Does Cs have larger atoms than Li?
Yes because Cs has more Electrons- which causes it to have more shells and this causes the structure to be larger. Li is small because it had a smaller amount of electrons- so it doesn't need a lot of shells which causes the shell to be smaller and the valence electron to be closer to the nucleus.
What element has 6 valence electrons in the 4th energy level?
This element is caesium (Cs), with the atomic number 56.
Which pair of atoms will have the same valence-shell electron configuration Se and Te Sr and Cs N and O H and He?
Se and Te
What has 55 electrons?
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.
How many electrons could a Cesium CS ion have?
55* 55 electrons and neutrons.
How many valence electrons does group 3A have?
Group One on the periodic table consists of * Li - Lithium * Na - Sodium * k - Potassium * Rb - Rubidium * Cs - Cesium All of these elements all have plus one (+1) valence electrons which means they have one too many so they will give it up when bonding occurs.
The alkali metals have how many valence electrons?
1
Is one valence electron very reactive?
