![]() Most solid nonmetals are brittle, so they break into small pieces when hit with a hammer or pulled into a wire. Nonmetals can be gases (such as chlorine), liquids (such as bromine), or solids (such as iodine) at room temperature and pressure. Nonmetals, in contrast, are generally poor conductors of heat and electricity and are not lustrous. Of the metals, only mercury is a liquid at room temperature and pressure all the rest are solids. ![]() ![]() The vast majority of the known elements are metals. Metals-such as copper or gold-are good conductors of electricity and heat they can be pulled into wires because they are ductile they can be hammered or pressed into thin sheets or foils because they are malleable and most have a shiny appearance, so they are lustrous. The distinction between metals and nonmetals is one of the most fundamental in chemistry. As you might expect, elements colored in gold that lie along the diagonal line exhibit properties intermediate between metals and nonmetals they are called semimetals. The heavy orange zigzag line running diagonally from the upper left to the lower right through groups 13–16 in divides the elements into metals (in blue, below and to the left of the line) and nonmetals (in bronze, above and to the right of the line). The semimetals lie along a diagonal line separating the metals and nonmetals. The metals are on the bottom left in the periodic table, and the nonmetals are at the top right. In their paper, the authors also write that Black Panther provides a good opportunity to discuss diversity in STEM, with King T’Challa’s sister Shuri, who leads Wakanda’s tech lab, offering “a shining example for the next generation of STEM leaders.\) The Periodic Table Showing the Elements in Order of Increasing Z “I couldn't believe how engaged they were.” In fact, she says, another set of students, who hadn’t sat the exam, heard about it and asked to be involved. But the students were “huge Marvel fans” and had been discussing the movie before class for weeks. “Usually when I teach the unit on the periodic table… students don't seem to be very excited,” says Appleby, a senior lecturer in chemistry at LTU. “I’d have been thrilled with a question like that as a student.” “It lets us talk about parts of the table not normally covered in undergraduate courses,” she says.

Meanwhile, one student picked up on the strength and hardness of vibranium, suggesting a close proximity to the same group as chromium, the hardest metal we know. The same expert suggested that vibranium’s amazing capacity to absorb sound and other vibrations (say, a hit from Thor’s hammer) would require “elaborate structures”, which are a common feature in the boron group in the periodic table. The expert the authors spoke to agreed, claiming that vibranium would almost certainly be “in radioactive land”. The same student also pointed to Wakanda’s use of vibranium as an energy source to support their claim. ![]() One student observed that in the film, vibranium “glows a blueish purple”, which resembles other radioactive elements like uranium. it changes genetic material), which could be indicative of radioactivity. Black Panther also shows vibranium’s strong mutagenic properties (i.e. Heavier elements, students noted, tend to be radioactive, making it possible that vibranium is as well. All agreed that vibranium would likely be located in the middle section of the periodic table, where the majority of metals are located. Vibranium’s likely location near the bottom of the table would also, in the words of one student, make it a “very heavy” element. As of January 2016, the seventh row of the periodic table was completed with the addition of four new elements, so a new element could begin an entirely new row. A common answer among the students was to place vibranium near the bottom of the periodic table.
