WebApr 28, 2024 · Oxygen is found in Period 2, Group 16. Apply the rule of the periodic table to your element. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. Each new period begins with one valence electron. Exclude groups 3 through 12. Webelectron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The …
WebWhen we look at an atom, we find that it has the same about of protons as it does electrons. So, if we look at oxygen, we see that its atomic number is 8, meaning that it has 8 protons. We can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8.
