00:01 Hi there.

00:02 We have a series of five true and false questions here that are all a little bit different.

00:07 They're not exactly related to each other, but let's check these out.

00:11 So in the first one, the mass of one proton is one amu.

00:17 So that is going to be true, especially if we are just talking one significant figure.

00:24 Because a proton, one proton is about 1 .007, et cetera.

00:35 Amu.

00:37 So if we're just looking at one significant digit, sure enough, it is one amu.

00:45 So first one is true.

00:47 Let's look at the next one.

00:49 Most metals are lustrous.

00:52 That is also true.

00:54 Metals are shiny.

00:56 They have luster, meaning they reflect the light.

01:00 So metals do have luster.

01:03 It's one of the properties of metals.

01:07 Whereas non -metals are not lustrous.

01:16 Let's change this middle word.

01:19 I was going to say metals have luster, but we will change this to r here.

01:27 All right, so metals are lustrous.

01:29 Look at number three...
