* protons - Atomic number
electrons - number of electrons is equal to number of protons k-41 is neutral
neutrons - Mass number - Atomic number
= 41 -19
= 22
Answer:
Be^2+ ion
Explanation:
Be(OH)x^y- ions and Be(OH)2 solid
Answer:
c. An ionic bond is much stronger than most covalent bonds
Explanation:
Ionic bonds are interatomic bonds that forms as a result of electrostatic attraction between two ions. For an ionic bond to be formed, one atom must have lost or gained electron from another that is transferring it. Ionic bonds typically form between atoms whose electronegativity differences are far apart.
Ionic bonds are usually stronger than other types of bonds due to the electrostatic attraction between ions.
One very distinct feature about ionic compounds is that they are conductors of electricity in either molten or aqueous. At room temperature, they are solids and contains no mobile ions.
