The answer is D.
The air inside the bubbles is gas and the solid forms the bubble.
Answer:
Z³⁺
Explanation:
The ion symbol can be depicted as Z³⁺ .
In this atom, the number of protons is 27 and the number of electrons is 24.
Protons are the positively charged particles within an atom.
Electrons are the negatively charged particles within an atom.
To find the charge;
Charge = Number of protons - number of electrons
Charge = 27 - 24 = +3
The atom is positively charged and it can be depicted as Z³⁺
The answer is A. Solids only
A density of a substance is constant. It is an extensive property, meaning it does not depend on the amount of substance because it is a ratio of mass to volume. No matter how much of each there is, they would always have a fixed ratio called density. For lead, the density is
Density = mass/volume
Density = 23.94 g/ 2.10 cm³
Density = 11.4 g/cm³
