Answer:
The density of tube A is greater then the density of tube B having more mass inside of the smaller area.
Explanation:
Answer: Group 16 elements form ions with a 2 - charge.
Explanation: Therefore each of these elements would gain one electron and become an anion with 1 - charge.

Answer:
For ²⁰⁸Pb²⁺ cation, the sum of the number of neutrons and electrons = 206
Explanation:
Lead, chemical symbol Pb, is a chemical element which belongs to the group 14 of the periodic table. The atomic number of lead is 82 and it is a member of the p-block.
The isotope of lead with the mass number 208, has 126 neutrons.
Since, atomic number = number of protons = number of electrons for neutral atom
Therefore, for ²⁰⁸Pb: number of electrons= 82
So, <u>for ²⁰⁸Pb²⁺ cation: number of electrons</u>= 82 - 2 = 80
<u>Therefore, for ²⁰⁸Pb²⁺ cation, the sum of the number of neutrons and electrons = number of electrons + number of neutrons = 80 electrons + 126 neutrons = 206.</u>
