Answer:
4
Explanation:
4 atoms on each size since hydrogen exist as a molecule
Answer:
the atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope
Explanation:
Average atomic mass = f1M1 + f2M2 + … + fnMn where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol.
Answer:
Li-F
Explanation:
Hydroxide is a negative ion, which can form ionic bonds with metals, but the bond in hydrogen and oxygen in hydroxide (OH-) is not ionic. It is covalent in nature.
C-C is clearly a covalent bond.
Li-F is an ionic bond.
Bond between H and Cl in H-Cl is covalent in nature. Because of the size difference hydrogen can not act as a cation. So it rather dissociates.
