Germanium, Astatine, Tellurium, and Arsenic are all _____. metalloids non-metals metals noble gases
zmey [24]

Answer:-

Metalloids

Explanation: -

Metalloids are elements with properties that are somewhat in between those that of metals and non metals. They have generally 4 or 5 electrons in their valence shell for up to the 4th period to be called a metalloid. From the fifth period 6 valence electrons can make an element metalloid.

From the sixth even 7 valence electrons can make an element metalloid

The electronic configuration of Germanium is

2,8,18, 4

So it is a metalloid.

The electronic configuration of tellurium,

2,8,18, 18, 6

So it is a metalloid.

The electronic configuration of Arsenic

2,8,18, 5

So it is a metalloid.

The electronic configuration of astatine

2,8,18, 32, 18, 7

So it is a metalloid.
