Electrons in the similar shell and the similar subshell have exactly same amount of energy.
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
Sulfur (S) has 6 electrons in its outermost shell and 2 electrons in its innermost shell, but the next shell also has 6 electrons, making it an example of having more than one shell occupied by electrons while still having the same number of electrons in each shell.
1st shell: 2 electrons, 2nd shell: 8 electrons, 3rd shell: 8 electrons, 4th shell: 4 electrons, 5th shell: 0 electrons, 6th shell: 0 electrons.
number of valence electrons
Shell 1: Two electrons Shell 2: Eight electrons Shell 3: Eight electrons Shell 4: Eighteen 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.
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
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.
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.
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.
Sulfur (S) has 6 electrons in its outermost shell and 2 electrons in its innermost shell, but the next shell also has 6 electrons, making it an example of having more than one shell occupied by electrons while still having the same number of electrons in each 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.
Elements that are contained within the same column in the periodic table are known as a group. All of the elements in the first group of the table have one electron in their outer shell.
