Which properties makes a metal a good material to use for electrical wires? A. Malleability and reactivity
B. Conductivity and ductility
C. Ductility and malleability
D. Reactivity and conductivity

D

Explanation:

Because a metal must reactive and able to conduct

B.Conductivity and ductility

Explanation.

Some metals are conductive and are ductile

Conductivity is the ability to have an electric flow

Ductility is the ability to bend

answer: mercury

explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
