Why is potassium so soft?

Alkali metals (Li, Na, K) are so soft that they can be cut with a sharp knife. This is possible because of the weak forces of attraction between the atoms.

Is potassium a metal?

Potassium is the seventh most abundant metal in the Earth’s crust. It makes up 2.4% by mass. There are deposits of billions of tonnes of potassium chloride throughout the world.

What atom has 19 protons 21 neutrons and 19 electrons?

This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons. To find out the number of neutrons you have to look at the atomic mass or weight of the element.

Why does potassium have 20 neutrons?

Because potassium has 3 isotopes, then we have to calculate for the different atomic weights of the isotopes: Potassium-39 – It has 19 protons and atomic mass is 39. Hence, number of neutrons is 39 – 19 which is 20.

What is potassium made of?

Most potassium is obtained from evaporite salt deposits containing sylvite (potassium chloride). It is also obtained from the minerals alunite and carnallite. Orthoclase feldspar is a very common potassium-bearing mineral. Potassium also can be obtained from the electrolysis of potash (KOH).

Why is potassium a metal?

Minerals mined for their potassium are pinkish and sylvite, carnallite and alunite. Hence, potassium is a metal. In fact, it is the most reactive metal in the periodic table. The ionization enthalpy of potassium is minimum.
