Which properties are characteristic of metalloids? High electrical conductivity and a high melting point
Low electrical conductivity and a low melting point
Intermediate conductivity and a high melting point
Intermediate conductivity and a low melting point

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

thats a little if u want the answer just look it up on google thats what i do haha : )

its first and third is your answer i did the qustion the fourth isnt right
