Group 1 elements have one valence electrons.
neutral
While electrons can be on any layer, a valence electron is an electron that is found in the outermost layer of an atom and that determines the atom's chemical properties.
Skin is an outside layer.
1. Periosteum (outside layer) 2. Medullary cavity (middle layer) 3. Endosteum (inner layer)
outside the nucleus in the electron cloud
Yes, it is easier to remove an electron from the outside shell of a K atom than from the outside shell of a Na atom. This is because potassium (K) is in Group 1 of the periodic table with one valence electron, which is further away from the nucleus compared to sodium's (Na) single valence electron in Group 2. The electron in the outer shell of potassium experiences less attraction to the nucleus, making it easier to remove.
electron cloud
The electron cloud, around the outside of the nucleus.
Electron
The electron cloud in an atom is located outside of the nucleus.
The three subatomic particles are the proton, the neutron, and the electron. Protons and neutrons are located inside the nucleus. Electrons are located outside of the nucleus in the electron cloud.
The subcutaneous layer of skin stores fat. The subcutaneous layer is the third layer from the epidermis, which is the outside layer.
