Neutrons = Atomic Mass - Number of Protons 1 of 8 How many times bigger than electrons are protons and neutrons? Protons and Neutrons are 1000 times bugger than electrons. 2 of 8 What is the name for the specific lines electrons orbit the nucleus on? The specific lines which electrons orbit the nucleus on are shells. 3 of 8 How many electrons can the first shell hold? The first shell can hold 2 electrons. 4 of 8 How many electrons can any shell after the first hold? Any shell after the first can hold 8 electrons. 5 of 8 What is each row in the periodic table? Each row in the periodic table is a different shell. 6 of 8 What is the equivalent of the number of electrons in the element's outer shell? The number of the group the element belongs to is the same as the number of electrons in the element's outer shell. 7 of 8 Why do atoms react with each other?
