Question

5. In a metal
=>all the electrons are free to move
=>all the electrons are bound to their parent atoms
=>there are no electrons
=>some electrons are free to move​

Answer 1

Answer:

the term "metal" is cast more widely to refer to all chemical elements in a star that are heavier than the lightest two, hydrogen and helium, and not just traditional metals. A star fuses lighter atoms, mostly hydrogen and helium, into heavier atoms over its lifetime. Used in that sense, the metallicity of an astronomical object is the proportion of its matter made up of the heavier chemical elements.In chemistry, the elements which are usually considered to be metals under ordinary conditions are shown in yellow on the periodic table below. The elements shown as having unknown properties are likely to be metals. The remaining elements are either metalloids (B, Si, Ge, As, Sb, and Te being commonly recognised as such) or nonmetals. Astatine (At) is usually classified as either a nonmetal or a metalloid

Answer 2

Explanation:

As all metals exhibit the metallic bond, they will most assuredly have free electrons. ... The electrons are very much free to move about and hence can carry heat or electrical current across the metal body.
