This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
Cesium, or Cs, has 1 valence electron.
Potassium has 1 electron in its outer energy level. When it forms a bond, it typically donates this electron to another element, leaving it with a full outer energy level.
Bromine has 7 electrons in its outer energy level, making it one electron short of a full outer shell.
One electron in outermost energy level.
A neutral sodium atom has 11 electrons. In its outer energy level, it has 1 electron. Sodium's electron configuration is 2-8-1.
Sulfur has 6 electrons in its outer energy level. This means it needs 2 more electrons to fill its outer energy level, for a total of 8 electrons.
this is a very easy question...the answer is the symbols be,mg,ca, and Sr on the periodic chart
it really depends i know for sure that its 3 electron clouds
It needs to lose one electron so that it can have 8 electrons in its outer orbital
I had a science question that asked: An electron ______ is the chemical symbol for the element surrounded by as many dots as there are electrons in its outer energy level. That is pretty much the same as yours. I put dot diagram... Meaning electron dot diagram
An energy level is the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. There are no full energy levels in an atom of hydrogen. The first energy level of any atom can hold 2 electrons. Hydrogen only has one electron and it is in the first energy level.
The halogens have 7 electrons in their outer shell desparate to gain the 1 electron to make a full shell of 8 electrons.
