Eight electrons in the 2nd shell of Br-
This is also the number of electrons in the 2nd shell of I-, Cl- and even F- !
The H+ ion has no electrons.
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
An Ion
your mom is an electron and i am her proton we keep eachother going
The H+ ion has no electrons.
Electrons per shell in uranium: 2, 8, 18, 32, 21, 9, 2
no electron is present in the outer most shell of hydrogen ion
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
It have an electron configuration of 2,8,8,SO it contains 8 electrons in it's outer shell.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
Carbon, as a non-metal wants to gain electrons to have 8 outer shell electrons. In its outer shell, carbon has 4 electrons. Therefore, a carbon ion picks up 4 electrons to become C-4
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
18
The shell closest to the nucleus of an atom can only hold up to two electrons.
Electrons in the outermost shell of an atom/ion are called valence electrons
18The use of the online site say there are eighteen electrons that are in the chloride ion CI-. The info is useful if you use the chloride in situation.
