Question

Isaiah has samples of two different elements, one metal and one nonmetal
Some properties of the samples are shown in the table below. Use the table to
answer Questions 2-3


What can Isaiah conclude about the identity of Sample A?

Answer 1

Answer:

1/ As a metal has higher melting point than a nonmetal has, we can guess that sample A is a metal.

2/ The melting point is over 1000 gradius Celcius: 1083 - it's not a low value. And as the sample conducts heat, it is not the element of period N3 in the periodic table, because elements in period 3 do not conduct electricity.

Explanation:

I can not see what the questions 2-3 in your picture is. I answered the question above the table: What can the student conclude about thenidentity of Sample A.
