Hi everyone for this problem. It reads the following images shows a reaction between a metal and a nonmetal. Alright. And our goal here is to identify which one of the two spheres is a non metal. Alright, so let's take a look here. Non metals are on the right and top of the periodic table and based off of trends between metals and non metals, they are usually smaller. Okay, so we'll write that they are usually smaller. They are more likely to gain electrons and they are less likely to lose electrons. Okay, So we'll put it more likely to gain electrons less likely to lose electrons. And this is all in comparison to metals. So looking at our reactant, we see our green sphere is larger than our orange sphere. And so because we know that they tend to be smaller, we can identify the yellow sphere as our nonmetal. Okay, so that's it for this problem. I hope this was helpful.

Textbook Question

The prefix eka- comes from the Sanskrit word for 'one.' Mendeleev used this prefix to indicate that the unknown element was one place away from the known element that followed the prefix. For example, eka-silicon, which we now call germanium, is one element below silicon. Mendeleev also predicted the existence of eka-manganese, which was not experimentally confirmed until 1937 because this element is radioactive and does not occur in nature. Based on the periodic table shown in Figure 7.1, what do we now call the element Mendeleev called eka-manganese?
