Instructions and Help about analyzing data graphing periodic properties

Its professor David let's talk about the periodic table pretty much everyone knows with this is even if they don't know much about chemistry. It's the periodic table of the elements which at first seems like a random arrangement of substances most of which sounds strange and foreign but the way the elements are arranged reveals many beautiful patterns that tell us about how nature operates. In the mid 1800s lots of chemists were trying to come up with a way to depict all the elements in table form and many formats were proposed, but it was the one by Dmitri Mendeleev that stuck because of how well it correlates data as well as its predictive powers. He arranged the elements into rows called periods and columns called groups elements that had similar behavior were put in groups together which helped to correlate existing data, and it also predicted the existence of elements that had never been seen before. With the gaps in the table Mendeleev said there must be elements that go in these spots, and he predicted some of their properties eventually these elements were discovered with the properties precisely as expected, and now we have all the metals, metalloids and nonmetals organized nicely it wasn't known at the time, but the reason elements in the same group behave similarly is because they have the same number of valence electrons. Look at group one for example, these elements all have one valence electron or one electron in their outermost shell. As you go down the table and n increases you gain a shell each time, but whichever is the outermost shell there is only one electron in it. Every element in group 2 has two electrons in its outermost shell and so forth this simple fact determines many characteristics about each element in ways we will continue to see as we learn more chemistry. There are some periodic trends that we can recognize when we look at the table. The first one is an atomic radius or the size of the atom. As we proceed downward on the table atomic size increases because we add shells. As we go to the right atomic radius decreases because we are moving within a shell and each element to the right has one more proton in the nucleus than the last, so there is a stronger electromagnetic attraction felt by the electrons and the radius shrinks, that means overall atomic radius increases going this way on the periodic table ionic radius is a little different, electrons repel each other so adding an electron makes an atom bigger. Taking one away makes it smaller ions with the same electron configuration will have their radii decrease as the atomic number increases next we look at ionization energy. This is the energy required to remove an electron from the atom. It will always be an electron in the outermost shell. The electromagnetic force that attracts the electrons to the protons drops off very quickly with distance so the farther away an electron is from the nucleus the easier it is to pull it away. This means the ionization...

What is graphing periodic trend?

Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties.

People Also Ask about graphing periodic trends lab answer key

How are elements on the periodic table arranged?

In the periodic table, the elements are arranged in horizontal rows called periods (numbered in blue) and vertically into columns called groups.

How can an elements properties be predicted?

Properties of an element can be predicted by using a periodic table. We can see many patterns in the physical and chemical properties of elements as we descend in a group or move across a period in the Periodic Table.

How do the properties of elements determine how they are arranged on the periodic table?

The chemical elements are arranged from left to right and top to bottom in order of increasing atomic number, or the number of protons in an atom's nucleus, which generally coincides with increasing atomic mass.

How do you graph atomic radius vs atomic number?

Remember I said we're looking at two different factors.

How are the elements arranged on the periodic table and how can properties be predicted?

The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties.

How do you graph periodic properties?

Create a graph of the atomic radius as a function of atomic number. Plot atomic number on the X axis and atomic radius on the Y axis. Remember to label the axes! Use a colored pen, pencil or highlighter to trace over the element's period (horizontal row on the periodic table).
