Cs - Cesium. It only has one outer elecron to lose to achieve a noble gas configuration. In this case it would be Xenon. Because it is well down the Periodic Table it is a relatively large atom and thus that outer electron is also well away from the nucleus and thus even easier to lose that electron because the nucleus does not hold it as strongly. Because of these factors it is more reactive than similar atoms of Li, Na, k, Rb.
What else can I help you with?
What is the effective nuclear charge for an electron in the outermost shell of a fluorine atom F?
The effective nuclear charge for an electron in the outermost shell of a fluorine atom (F) is approximately +7. This charge results from the balancing of the positive charge of the nucleus with the shielding effect of inner electrons.
How many electron in its outermost level do argon have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
What is the size of the atom in helium?
The size of an atom is typically measured in terms of its atomic radius, which for helium is approximately 31 picometers (pm), or 0.31 angstroms. This corresponds to the distance from the nucleus to the outermost electron cloud in a helium atom.
An atom that has gained one electron has a charge of?
-1, since each electron has a charge of -1.
Can you give me a sentence with the word electron?
The electron is a subatomic particle with negative elementary charge.
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
How many electrons are in the outermost electron shell of a phosphorus atom?
There are 5 electrons in the outermost electron shell of a phosphorus atom. Phosphorus has an electron configuration of 2, 8, 5.
How many electrons are in the outermost orbital in one atom of sodium?
One atom of sodium has one electron in its outermost orbital.
What is an electron in the outermost energy level of an atom?
An electron in the outermost energy level of an atom is called a valence electron.(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)These electrons determine the chemical reactivity of the atom.the valence electrons
What do the outermost electrons of an atom and inner electrons?
calculate the current due to revolution of electron in the outermost orbit of the Na atom, if the time period of revolution of electron is 2 micro second
An electron that is found in the outermost shell of an atom and that determines the atoms chemical properties?
This electron is a valance electron.
Consider the element Phosphorus 30P. How many electrons are in the outermost electron shell of a phosphorus atom?
There are 5 electrons in the outermost electron shell of a phosphorus atom. Phosphorus has the electron configuration 2-8-5, so it has 5 electrons in its outermost shell.
An atom contains seven electrons in its outermost energy level the atom is what?
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
When is electron a valence electron?
A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.) It is an electron in the outermost shell of the atom.
What happens when an atom loses an electron form its outermost shell?
It becomes a positive ion, and also connects with the atom that stoles its electron.
What kind of a tomb tends to lose one electron?
An atom with single electron in its outermost shell
In which case is an atom least likely to bond with an atom?
If it's outermost electron shell is filled.
