helium has completely filled orbitals and does not react with any element.
because potassium is the total opposite of ionic bond
Potassium and helium do not form an ionic bond because they belong to different groups on the periodic table. Potassium is a metal in group 1, while helium is a noble gas in group 18. Due to their large difference in electronegativity and stability, they are unlikely to transfer electrons to form an ionic bond.
Potassium chloride (KCl) has an ionic chemical bond.
The pair of elements that is most likely to form an ionic bond are potassium (K) and fluorine (F). This is because potassium is a metal (it can lose electrons) and fluorine is a nonmetal (it can gain electrons), making them likely to transfer electrons and form an ionic bond.
Potassium iodide (KI) has an ionic bond.
Ionic
Potassium (K) and Bromine (Br) are likely to form an ionic bond, where potassium will donate its outer electron to bromine, resulting in the formation of KBr (potassium bromide) compound. Ionic bonds form between elements with large differences in electronegativities, which is the case for K and Br.
Potassium sulfate forms an ionic bond, it is composed of ions
Potassium bromide has ionic bond.
Helium has a stable (full) valence shell (1s2) which means that it will have a high ionization energy (the energy required to remove an electron). In fact, helium has the highest ionization energy of any element. However, this does not mean that helium cannot form ions. It just means that it will require a lot of energy to do so and this does not happen under normal conditions.
Yes, KI (potassium iodide) is an ionic compound. It is formed between a metal (potassium, K) and a nonmetal (iodine, I) through ionic bonding, where potassium donates its electron to iodine to form an ionic bond.
Yes, K2S (potassium sulfide) involves an ionic bond. Potassium (K) is a metal and sulfur (S) is a nonmetal, resulting in the transfer of electrons from potassium to sulfur to form ions, leading to the formation of an ionic bond.
