The substance that is a diatomic molecule is B. O2 Oxygen.
The answer is B. The less mass then the less the gravity pulls on it
31 protons 31 electrons and 39 nutrons
Answer:
You just have to take the periodic table of the elements, take the element that interests you. Then, you look at the formula of the element, at the top left you find the number of neutrons and protons and at the bottom left you find the number of protons. Then you just have to make the number from the top left minus the number from the bottom left.
Explanation:
Hello,
In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
Hope this helps!!!! Happy Holidays!!!! (:
