The answer is (4) 4. Germanium is a main group element in group 4A. Therefore, like carbon, it has 4 valence electrons in the ground state.
Height of wave - amplitude
Higher the pitch - higher the frequency
Louder - higher the amplitude
bottom of the wave - trough
distance from crest to crest - wave length
top of the wave - crest
Answer:
nacl with water
they are capable of conducting electricity
Hey there !
The answer would be C. Is when electrons cannot nice through objects easily.
