yes to form k+
Selenium does not typically form a positive ion. It tends to form negative ions (anions) by gaining electrons to achieve a stable electron configuration. Potassium, titanium, and lithium are more likely to form positive ions (cations) by losing electrons.
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
The electrical conductivity of potassium is high because it is a metal. Potassium atoms can easily lose electrons to form positive ions, allowing electric current to flow through a potassium sample.
Positive ions, or cations, are formed when atoms lose one or more electrons. This typically occurs in metals, such as sodium (Na), potassium (K), and calcium (Ca), which have a tendency to donate electrons to achieve a stable electron configuration. Nonmetals can also form positive ions under certain conditions, but they are more commonly known for forming negative ions, or anions, by gaining electrons.
Elements that tend to form positive ions (cations) include metals such as sodium (Na), potassium (K), calcium (Ca), and magnesium (Mg). These elements typically lose electrons to achieve a stable electron configuration.

The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
Elements can form a positive ion by losing electrons to achieve a stable electron configuration. Metals are more likely to form positive ions by losing electrons, while nonmetals tend to gain or share electrons to form negative ions.
Those to the far left of the periodic table Elements belonging to Group1 of the modern periodic table form positive ions easiest. They are called alkali metals because of their tendency to form strong bases. They include Hydogen, Sodium, Potassium, etc.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Usually if potassium has a charge, it is +1.
Positive ions form when an atom or group of atoms loses one or more electrons.
