How many valance electrons do most elements need to have a stable electron configuration?
8 valance electron
What is the number of valence electrons for the elements in group 1?
Elements in group 1 (alkali metals) have 1 valence electron. This single electron is in the outermost energy level of the atom, making these elements very reactive and likely to lose this electron to achieve a stable electron configuration.
What element has the configuration 2 8?
Neon - one of the stable and unreactive elements of group 8.
How many elements does the outer electron have?
An electron is not an element.
What group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
What are the column 8 elements called?
Column 8 elements are known as the noble gases or inert gases. They include helium, neon, argon, krypton, xenon, and radon. These elements have a full outer electron shell, making them stable and nonreactive.
How many electrons are in level 2 of mercury?
electron configuration: 2, 8, 18, 32, 18, 2
In sodium fluoride sodium has the electron configuration of which other element?
Sodium fluoride has electron and ionic elements. This is taught in science.
Which group in the periodic table would need only 1 electron to be stable?
The elements in Group 7A (halogens) on the periodic table would need only 1 electron to achieve a stable electron configuration by filling their outermost shell with 8 electrons. For example, elements like fluorine, chlorine, and bromine each need only 1 more electron to reach stability.
What is the maximum number of electrons that a representative element can possess?
The maximum number of electrons that a representative element can possess is 8. This is because the outermost electron shell of these elements can hold a maximum of 8 electrons in order to achieve a stable electron configuration.
Neon is an inert element.why?
Neon is inert because it has a full outer electron shell, making it stable and unlikely to form chemical bonds with other elements. Its electron configuration of 2-8 gives it no need to gain, lose, or share electrons with other elements to achieve stability.
How many completely full electron shells do the elements in the third row contain?
Elements in the third row of the periodic table have 3 completely full electron shells. This means they have all 8 electrons in the first shell, all 8 electrons in the second shell, and all 18 electrons in the third shell.
