Almost all properties are common to elements within a single group on the periodic table. They react with water in the same way, they have the same number of valence electrons thereby having the same valency, the number of shells in the atom of the element increases by one as we move down the group.
In general, they have the same chemical properties as chemical properties depend on the number of electrons in the valence shell i.e. the outermost shell in the atom of an element.
Explanation:
1.
i. Measure the initial volume of water in a graduated cylinder.
ii. Now submerge the irregularly shaped metal into water in a graduated cylinder.
iii. Measure the final volume of water.
iv. The difference between the final volume and the initial volume is the volume of the irregularly shaped metal.
2.
When adding the irregularly shaped metal into the glass graduated cylinder. Make sure that the irregularly shaped metal is completely submerged into the water.
Explanation:
K2O Now the cation is the element at the front so it would be K2 because the 2 belongs with the K which is Potassium and now Anion is the last element O for oxygen
The density of the metal is 7.11 g/mL.
<h3>What is the density of the metal?</h3>
The term density of the metal is defined as the ratio of the mass to the volume of the metal. The volume of the metal was obtained by the displacement method. The volume of water that was displaced is the volume of the metal.
Hence;
Mass of the metal= 56.188g - 1.429g = 54.759 g
Volume of the metal = 33.6mL - 26mL = 7.70 mL
Density of the metal = 54.759 g/ 7.70 mL
= 7.11 g/mL
