When forming ions, all metals have a (+) positive charge. Which of the following BEST explains why?
(a.) Metals are known to add protons to their nuceili and become
positively charged.
b. All metals tend to lose one or more valence electrons giving them a
positive charge.
c. All metals gain electrons giving them a positive charge.
d. Metals are known to lose protons and gain neutrons resulting in a
positive charge.

b is the correct

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
