Potassium (K) is an alkali metal, placed under sodium and over rubidium, and is the first element of period 4. It is one of the most reactive elements in the periodic table.
Answer:
because they emit liquid waste wich is later dumped into the ocean causing a lot of harm and many fatalities in sea life
Explanation:
As you go down a group, the atoms get bigger. The bigger the atom, the more unstable it is. The more unstable it is, the more reactive the atom will be. So, as you go down a group, the nonmetals will become more reactive.
Since the particles can move, the liquid<span> can flow</span> <span>and take the shape of its container. Some insects, such as pond-skaters, are able</span><span> to walk on water without sinking. This is because the forces of attraction between the water particles pull the particles at the surface together.</span>
The purpose of an universal indicator is to test wether a solution is acid or if its a base. It changes colors according to the PH's. It helps a lot in the indication of a chemical reaction because it can say if <span>each component loses or gains protons depending upon the acidity or basicity of the solution being tested.An universal indicator can say if a determined solution proves to be endothermic or exothermic. If the solution is not tested as acid or base then we cannot knwo if there will be an endothermic reaction or an exhotermic one</span>
