What does it mean when a metal has low electronegativity?
Have low electronegativities: Electronegativity is referred to the ability of the atom to attract electrons to form a chemical bond. So high electronegativity means it will attract electrons very easily, and low electronegativity means less ability to attract electrons. Thus, metals have low electronegativity.

What are the two types of materials?
The elements further divided into two material called Metals and Non-Metals. Just look around yourself you are surrounded by the elements, now the question is can you differentiate what is metal or non-metal? Is copper wire or aluminium window is metal or non-metal? So in science, there are some properties mainly physical and chemical properties which help us to distinguish between the two. For example suppose there is cow and dog, although both are animals, still, we can differentiate them easily by just seeing them. Both look completely different to each other, and we can easily tell that look this is a dog and that is a cow. Before differentiating between two let’s first understand what actually they are?
