A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Elements in the same column as sodium in the periodic table, such as lithium and potassium, also contain one outer electron.
Elements in the same group as sodium (Group 1) all contain the same number of outer electrons, which is one. Therefore, there are six elements in the same group as sodium: lithium, potassium, rubidium, cesium, francium, and hydrogen.
There are 2 electrons in the valence orbital of a Magnesium atom.
95 electrons, two of them are in the outer orbit.
Hydrogen ions in water have zero. If you just mean neutral atoms in gas phase, then hydrogen, helium and lithium.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
A neutral atom of oxygen has 6 electrons in it's most outer orbit. Generally, if you count horizontally from left-to-right on the periodic table, you get the number of electrons in its' most outer orbit. You start every row with 1, of course. :) Hope that helps!

The reactivity of an atom is due to its number and arrangement of __________ in the outer energy level (or orbit). your question was confusing but I was able to interperet it. the answer is Electrons
Elements in the same column as sodium in the periodic table, such as lithium and potassium, also contain one outer electron.
All elements in the oxygen family have 6 electrons in the outer orbit.
Oxygen has 6 valence electrons. These are in the outer orbit.
A lithium atom has one electron on the outer shell. This is because there is 2 electrons maximum on the inner shell, so there is one left over for the outer shell. Hope you understand now xx
