Stars on the main sequence fuse hydrogen into helium via a six-stage sequence of reactions
Answer:
volume
Explanation:
the mass is the same on earth as it is on the surface of the moon. The weight is determined by the force of gravity. The density is the thickness. But the volume is not a factor.
Answer:
Beryllium
Explanation:
They are in the same group
When an atom donates electrons and other gains electrons, they form ions and the bond is called the ionic bond. When the atoms share electrons between them, they form a molecule, and the bond is called the covalent bond.
The atoms can share one, two or three pairs of electrons in the same bond. If one pair is shared it's called a single bond or a covalent simple; if two pairs are shared it's called a double bond or a covalent double, and if three pairs are shared it's called a triple bond or a covalent triple.
If this helps, please mark me as brainly, if not thats ok. im just here to help you get good grades. :D
Answer:
In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). ... The concept is also useful for describing the chemical bonds that hold atoms together.
