Each atom consists of a central nucleus and several shells that contain electrons. The outermost electrons are called valence electrons. Most atoms are stable with a configuration of eight valence electrons. This is known as the octet rule. How many valence electrons does each atom have? * 1 point

Step-by-step explanation:

Not only did outermost electron determine the valence electron, but also periodic table. whatever group they fall into in periodic table each valence electrons present in a particular atom e.g K and Ca belong to group 1 and 2 respectively and k has 1 and Ca have 2 in each outermost electron
