Potassium lose an electron.
Potassium is more likely to lose its electron to become a positive ion.
Chlorine has a high electronegativity, meaning it has a strong tendency to attract electrons. This property makes it likely to form a compound with an alkali metal through ionic bonding, where the alkali metal loses an electron to chlorine to achieve a more stable electron configuration.
Fluorine is similar to chlorine.
Elements in Group 17 such as fluorine, chlorine, bromine, and iodine are most likely to gain electrons because they only need one electron to complete their outermost energy level and achieve a stable electron configuration similar to a noble gas.
Carbon and chlorine are most likely to form a covalent bond. Sodium and potassium typically form ionic bonds due to their tendency to lose electrons, while copper and argon are unlikely to bond. Carbon and chlorine, being nonmetals, are more likely to share electrons in a covalent bond.
Potassium lose an electron.
Chlorine is MUCH more likely to fill its outermost orbital by gaining electrons.
Iodine is not reactive with potassium chloride in an aqueous solution because iodine is less reactive than chlorine. Chlorine is more likely to react with potassium to form potassium chloride, leaving the iodine unreacted.
Chlorine most readily accepts electrons among silicon, sulfur, chlorine, and phosphorus. Chlorine is a halogen and has a high electron affinity due to its high electronegativity, making it more likely to accept electrons to achieve a stable electron configuration. Silicon, sulfur, and phosphorus are nonmetals with varying electron affinities but are generally less likely to accept electrons compared to chlorine.
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.
An element with 7 valence electrons is likely in Group 17 of the periodic table, such as chlorine. With 74 neutrons, it corresponds to the isotope chlorine-81.
Molecules that have a high tendency to gain or lose electrons are most likely to become ions. Common examples include metals, such as sodium and potassium, which tend to lose electrons to form positive ions, and nonmetals, such as chlorine and oxygen, which tend to gain electrons to form negative ions.
Chlorine is more likely to accept electrons than donate them due to its electronegativity. In its natural state, chlorine tends to gain one electron to achieve a stable electron configuration, forming a chloride ion.
The group likely to react with chlorine to form XCl is the alkali metals group, such as sodium, potassium, or lithium. Alkali metals readily form ionic compounds with chlorine by donating an electron to chlorine, resulting in the formation of XCl.
Chlorine (Cl) will most likely bond with carbon to form carbon tetrachloride (CCl4) through covalent bonds. Chlorine is capable of accepting electrons to complete its valence shell, while carbon can donate electrons to bond with chlorine.
Potassium is more likely to lose its electron to become a positive ion.
