Beryllium, Magnesium, Calcium, Strontium, Barium and Radium
An ionic bond is formed between a metal and a non metal. The METAL loses an electron (or electrons) and it becomes positively charged.
An element that tends to give up electrons has a positive oxidation number. This is because when an element loses electrons, it becomes positively charged.
Aluminum and fluorine form an ionic bond because aluminum loses electrons to become a positively charged ion, while fluorine gains electrons to become a negatively charged ion. This transfer of electrons results in the electrostatic attraction between the two ions.
When a lithium atom reacts with a fluorine atom, the lithium atom loses an electron to form a lithium cation and the fluorine atom gains that electron to form a fluoride anion. This results in the formation of lithium fluoride (LiF), an ionic compound.
Potassium is the element that is most easily reduced because it has a low ionization energy and readily loses an electron to form a +1 cation.
Lithium loses one electron when it reacts
Magnesium is the element that loses 2 atoms when reacting, reacts slowly with water, and can conduct electricity.
a binary ionic compound
Iron reacts with oxygen to form Fe2O3 also known as rust. Oxygen requires two electrons to fill it's valence shell so iron loses electrons.
An ionic bond is formed between a metal and a non metal. The METAL loses an electron (or electrons) and it becomes positively charged.
Argon
An element that tends to give up electrons has a positive oxidation number. This is because when an element loses electrons, it becomes positively charged.
Generally metals lose electrons and nonmetals gain electrons.
