Hg = (3.2 : 4.2) x 100% = 76.19%
O = (1 : 4.2) x 100% = 23.81%
I think the correct answer from the choices listed above is the third option. <span>Natural gas is a great alternative to electricity for cooking is the statement that describes the use of a nonrenewable resource. Natural gas is a nonrenewable resource since it takes a lot of time to be able to form this. Hope this answers the question.</span>
Answer:
C. chloride i hopeit's right..
Ca²⁺ion has a lower ratio of charge to volume.
The charge density of an ion is defined as the ratio of the charge of an ion to its volume. Scandium ion has high charge density than calcium ions. The charge density of an ion is defined as the ratio of the charge of an ion to its volume.
Charge density also depends on the size of the ion and valence electrons. The volume of an ion increases with its size. It is inversely proportional to ion volume and directly proportional to charge magnitude. Scandium and calcium are IV periodic elements with atomic numbers of 21 and 20 respectively. Scandium loses three electrons and has a +3 charge and calcium is a divalent cation. Hence, the Scandium ion has high charge density than the calcium ion.
