the energy of red light is not sufficient to eject electrons from the valence shell of the potassium atom.
No reaction, since zinc, which is lower in the electropositive series than potassium, cannot displace potassium from its compounds.
true because you need oxygen to breath
Alkali metals, such as sodium and potassium, are highly reactive and tend to combine quickly with other elements in nature to form compounds. This is because they have only one valence electron, which they easily lose to achieve a stable electron configuration. Therefore, it is rare to find pure alkali metals in their elemental form in nature.
you cannot mine pure potassium but you can mine potassium chloride or as it as Potash ore. These mines are found allover the world where there have been ancient sea that have evaporated and let potassium salts.
Protons and electrons cannot be disintegrated.
Because both sodium and potassium have one electron in their outermost shells, and they need to donate these electrons to become stable. In other words, both of these elements will become positive ions, and neither will accept an electron from the other. They need to bond with atoms which need another electron to fill its outer shell, such as cholorine. Both sodium chloride (NaCl) and potassium chloride (KCl) exist because chlorine will accept the extra electrons from sodium or potassium atoms. Bottom line: you cannot bond two atoms that both need to lose electrons to become stable because neither will accept the extra electron from the other.
because an electron microscope has a vaccum chamber which cannot allow oxygen to pass
It is because unlike sodium carbonate potassium carbonate is fairly soluble in water and it does not forms precipitate.
Sodium and Potassium belong to group one of the Periodic table. They both contain one electron in their outer shell. They form a chemical bond by donating the outer shell electron to another atom. The other atom will tend to accept electrons rather than donate them. Since sodium and potassium both donate electrons they cannot form a chemical bond with each other.
This question cannot be answered because if you neutralise citric acid you will get a citrate, not a nitrate. To get potassium nitrate you will need the alkali potassium hydroxide and nitric acid.
Ther is no reaction that occurs because potassium is a more active metal and cannot be displaced by the iron (a weaker metal)
electrons are in orbits protons are in nucleus an electron keeps revolving in the orbit because of force of attraction but this electron cannot come into the nucleus where proton and neutron reside.
We cannot accurately predict where in the electron cloud electrons can be found because of the Heisenberg uncertainty principle. This principle states that it is impossible to simultaneously know the exact position and momentum of an electron. As a result, we can only describe the probability distribution or the likelihood of finding an electron in a particular region of the electron cloud.
No silver cannot react. It is less reactive than potassium
No reaction, since zinc, which is lower in the electropositive series than potassium, cannot displace potassium from its compounds.
The electron is an elementary particle. This means that it cannot be broken down further. Therefore, an electron does not have a "core".
