![]() ![]() If you know whether the things reacting are Properties of metals and some properties of nonmetals. And these things that straddle this yellow line right over here, these things that are in this kind of bluish-green kind of color, these are sometimes viewed as metalloids because they have some There's subclassifications of the metals but generally speaking,Īll of these things that you see right over here below this scratchy yellow line have the properties, generally speaking, of conducting electricity,īeing malleable, being solid at room temperature. Periodic table of elements has different colors is that Now everything else, you can consider in some form to be a metal and the reason why this They don't tend to formĪny of these bonds. Them as a subclass of nonmetals and they tend to be very inert, they don't interact with other things. Periodic table of elements put them in their own color 'cause then you could view Talked about in other videos, these are the noble gasses. And it is the case that generally speaking at room temperature, theyĬonduct electricity well. Periodic table of elements, everything in this yellowĬolor that we have here, so hydrogen and carbon and nitrogen and oxygen and fluorine,Ĭhlorine, I could keep going, these are all nonmetals. Look at the color code from the folks who made this The right of this yellow line is a nonmetal and if you Little scratchy yellow line I'm drawing is trying to indicate. Metals from the nonmetals? Well that's what this Periodic table of elements, how do you divide the They are not going toĬonduct electricity well. Nonmetals, generally speaking, at room temperature are often not solid, they're often times gasses. Now what do you think the properties of nonmetals are going to be? Well generally speaking, they're going to be the opposite of this. There's exceptions to this, they are solid at room temperature. Which is just a fancy way of saying that you canīend them without breaking. Ones that are in between, what are the properties of metals? Well, generally speaking, What are the nonmetals and maybe what are the The periodic table of elements what are the metals and Going to think about things as metals and as nonmetals. I'm going to introduce a broad classification of the elements, and in general, we're just To dig a little bit deeper and talk about the types of bonds that are likely to be formedīetween different elements. ![]() Idea of bonds between atoms, and we talked about the types of bonds, ionic, covalent and metallic. In a previous video, we introduced ourselves to the We can't do anything to change the polar covalent bond into an ionic bond because it's the identity of the elements which is determining the type of bond. So hydrogen and oxygen do not form an ionic bond simply because they do not have a large enough electronegativity difference. This would place the hydrogen oxygen bond in the polar covalent range instead of the ionic range. Hydrogen's electronegativity value is 2.20 while oxygen is 3.44, which result in a difference of 1.24 (3.44 - 2.20 = 1.24). Using the Pauling scale of electronegativity we need a difference greater than 2.0, x > 2.0. The very electronegative atom in an ionic bond will attract electrons to itself to such a degree that it removes electrons from the other, less electronegative atom. A large electronegativity difference means that a very electronegative atom was bonded with a not so electronegative atom. So it's unclear as of now what it is.įor an ionic bond to happen, the electronegativity difference between the two bonding atoms has to be large enough. Which would be a break from the trend of the group of unreactive gases at normal conditions. It's in the same group as the noble gases (which are nonmetals), but has been hinted that it may be solid under normal conditions and significantly reactive. ![]() So since so few atoms of Og have been created it's hard to say conclusively what it's properties are as of now. It was given the "-on" suffix since it belongs to group 18 along with the noble gases who all have suffixes of "-on". In 2016 is was officially decided to name it Oganesson (which the chemical symbol of Og) after Russian physicist Yuri Oganessian whose team helped synthesize superheavy elements 107 through 118. Ununoctium was a placeholder name for element 118 giving by the IUPAC in 1979 which was intended to be used until its discovery was confirmed since the people who discover an element gain the right to name it. Firstly, element 118 is no longer named ununoctium and has not been named so since 2016. ![]()
