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 valence electrons does a chlorine atom have if its electron configuration is Ne3s23p5?
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
Electron configuration for francium?
7s1 because the definition of valence electrons are the outermost s and p electrons therefore in this case there is only an outermost s electron and therefore the answer is 7s1. NOTE:IT DOES NOT INCLUDE THE D AND THE F ELECTRONS!!!!Other valence configuration examples include;Nitrogen : 2s2 2p3Chlorine : 3s2 2p5Zinc: 4s2Bromine: 4s2 4p5
Why do group 17 elements typically form a negative ion?
You mean group VII of the periodic table? Group VII elements are known as halogens and they form -1 ions readily is as they only require 1 more electron to obtain full electronic configuration. They all lack 1 valence electron in their valence shells. Full electrion configuration means that there aren't any valence electrons.
How many valance elctrons does phosphorus have?
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
How does the electronic configuration of sodium shows the group and period in the periodic table?
The electronic configuration of sodium is [Ne]3s1. Sodium has one valence electron. And it belongs to group 1. The valence electron is in 3s orbitals and it tells that sodium is a s-block element and is in period 3.
Explain why there should be a connection between an element electron configuration and its location on the periodic table?
An element's electron configuration determines its location (group) in the periodic table. It tells us how many valence electrons (s and p sublevel).
What element has 2 electron shells and 4 valence electrons?
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
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 valence electrons does ribidium have?
Rubidium is in group 1. The electron configuration is [Kr] 5s1. It has one valence electron.
What is the general valence shell configuration for the elements in group 1A?
Valence electron configuration in group 1A: ns1 in which n=1, 2, 3, 4, 5, ... etc. Starting with Hydrogen, H, electron configuration: 1s1 followed by Lithium, Li, electron configuration: (1s2), 2s1 (non valence electrons in () brackets)
If an element has 1 valence electron what group is it in?
That element would be in the Alkali Metals (group one)
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
How many valence electron does a group 18 element have?
8
What is the valence electron configuration for boron?
Boron exists in period 2, group 13 (IIIA) of the periodic table, with valence of 3 electrons in the outer shell. The electron configuration of boron is 1s22s22p1
How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
How many core electron and valence electron does a nitrogen has?
Nitrogen is the element located in group 15, period 2. Thus, its electron configuration is 1s2 2s2 2p3. That means that 2 is its valence shell and 1 is its core shell. Therefore, nitrogen has 2 core electrons and 5 valence electrons.
