The outer electron configuration of an alkali metal has?
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
What element in the 3rd period forms minus 1 ion?
Chlorine (Cl) in the 3rd period can form a -1 ion by gaining an electron to achieve a full outer electron shell (electron configuration of 2,8).
Is rubbidium conducts electricity?
Rubidium is silvery metal with a valence electron in its outer shell. It conducts electricity.
What happens to the electrons in the outer shell when the alkali metals react with other elements?
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.
When a group 1 metal reacts what happens to the outer shell electrons of its atoms?
When a group 1 metal reacts, its outer shell electron(s) are transferred to another atom or shared in a chemical bond. This results in the metal ion having a full outer shell of electrons, usually achieved by losing one electron to become stable with a +1 charge.
What is the group that has one electron in its outer level?
alkali metal
When an alkali metal reacted with a non metal what happens to the loan outer shell electron?
The electron outside the shell donate its electron to the one inside the shell
The outer electron configuration of an alkali metal has?
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
What is each period of the table begins on the left with a?
All periods begin with an alkali metal, excepting the first which begin with hydrogen..
Why is sodium a metal whereas carbon a non metal?
Sodium is a metal because it has one electron in its outer shell, making it highly reactive and likely to lose that electron to achieve a stable electron configuration. Carbon is a nonmetal because it has four electrons in its outer shell, making it more stable by either gaining, losing, or sharing electrons to achieve a full outer shell.
What are the 3 what are the three key differences between the elements sodium and chlorine?
Sodium is a metal, whereas chlorine is a non-metal. Sodium has a single electron in its outer shell, while chlorine has seven electrons in its outer shell. Sodium is highly reactive and readily loses its outer electron, whereas chlorine is highly reactive and readily gains an electron to complete its outer shell.
Why is a metal with three outer electrons a better conductor that a metal with one outer electron?
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.
Does alkali needs to gain one electron to have a completely outer shell?
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).
How many electrons will a non metal generally have in its outer shell?
non-metals have between 3 and 8 electrons in the outer shell. You can tell how many they have by looking at which period they're in on the periodic table, period 13 elements have 3, period 15 elements have 5 ect.
What element in the 3rd period forms minus 1 ion?
Chlorine (Cl) in the 3rd period can form a -1 ion by gaining an electron to achieve a full outer electron shell (electron configuration of 2,8).
Which element has an atomic number of 45?
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.
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.
