Sn has how many core electrons

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. The highest occupied electron shell is called the valence shell, and the electrons occupying this shell are called valence electrons. The chemical properties of the elements reflect their electron configurations.

For Xe and Br the s and p electrons are in the same shell, but d electrons are not in the outermost shell. Pure aluminum Ductile and highly malleable, aluminum can be drawn into wire or rolled into thin foil.

Names for different groups on the chart. Group 1 column 1 Alkali Metals.

Group 2 column 2 Alkali Earth Metals. Group 7 column 7 Halogens. Group 8 column 8 Nobel Gases. All elements in a vertical. Valence electrons are the number of electrons in the outermost energy level that has electrons in it. All elements that have the same number of valence electrons in their outer shell will be in the same column also call a group or family. All elements in the same column will react similarly chemically. See Figure Notice that the numbers of s and p electrons the only sublevels that will ever have valence electrons in them are always the same in a column.

The only difference is the n number.
