Electrons in the similar shell and the similar subshell have exactly same amount of energy.
They have the same number of valence electrons, or electrons in the outer electron shell. This allows them to react with certain elements.
They have the same amount of valance electrons.
Elements in the same group have similar properties because they have the same number of electrons in their outermost shell
Electron configuration - they have the same number of elements in their outer 'electron shell'. This induces them to have similar bonding properties, and so elements in the same group are chemically similar.
number of valence electrons
They are orbiting the same nucleus at the same distance.
amount of electrons in their outermost shell that their shell can hold in relative of one to maximum amount their outer shell can handle in a stable element.
They both have same number of electrons, i.e. 4 in their valence shell.
They have the same number of valence electrons, or electrons in the outer electron shell. This allows them to react with certain elements.
Their outermost electrons are in the same shell. For example, Helium and Hydrogen have 1 and 2 electrons respectively, and these electrons exist within the first electron shell. Lithium has 3 electrons and the third of these electrons is in the second electron shell, and so, it is a member of the 2nd period of the periodic table.
They have the same amount of valance electrons.
Number of valence electrons, that is, the number of electrons that the outer shell of an atom can hold. Ex. All halogens can have 7electrons in their outer shell. All gases have a full octet, eight electrons.
Elements in the same group have similar properties because they have the same number of electrons in their outermost shell
The row is called the period. Each element in the same period has the outermost electrons in the same shell (energy level). For example, the elements in the 3rd period all have the outermost electrons in the 3rd shell.
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
There are 12 electrons in the electron shell of magnesium, the same number as protons. As for the outermost shell, it would be 3s2, meaning there are two electrons in the third "s" shell.
