How can you use the Periodic Table to help you compare and contrast different elements?

Answer 1

you can find almost everything you need to know about any element with the Periodic Table. The number of electrons, average Atomic Mass, number of protons and neutrons. Based on it's position you can find its electron configuration. Also you can estimate the ionization energy, electronegativity, what category of elements they are. Also by looking at the cloumns of the table tells you what atoms have similar chemical characteristics. There's tons more
Element's name, symbol, atomic number, atomic mass, whether it is a metal, non-metal, metal, or a metalloid. It also can tell you the number of valence electrons, its reactivity, and can help you infer about its size. ^ I think.
A. Number of electrons and protons (atomic number)

B. Number of neutrons

C. Period

D. Group

Ex.:

8 16.00

O

Oxygen

8 is the Atomic Number (the number of protons in one atom of the element)

16 is the Atomic Mass (total number of protons and neutrons in one atom of the element)

Another way to tell the Atomic Number and the Atomic Mass is that the Atomic Number is always smaller then the number of Atomic Mass

Protons: 8

Electrons: 8

Neutrons: 8

To know the number of neutrons, we have to do some math.

Atomic Mass equal the number of protons plus neutrons.

So we have to take the number of Atomic Number MINUS Atomic Mass.

16 - 8 = 8

So the number of neutron is 8.

Oxygen group: 16 Oxygen period: 2

From the periodic table, we can also know the name of the element and what is it called in the scientific way. Also some chemical and physical properties are deductible.
Obviously, you can find out the name and chemical symbol of an element.

You can learn the Atomic/Proton number of the element, which is the number of protons in the nucleus of the element, as well as the number of electrons in the neutral atom.

You can learn the mass number, which tells you the weight of one atom of the element (which is actually just the mass of the protons and neutrons in the nucleus, as electrons weigh next-to-nothing) and you can use this number to work out the number of neutrons in the most common isotope of the atom by doing,

Mass Number - Proton Number = No. of Neutrons.

You can find out what group the atom is in (either 1-8, transition metal, lanthanide or actinide) and you can use this to work out the number of shells/rings/energy levels the electrons in the atom have. You can also use this to find the number of electrons in the highest energy level of the electrically stable atom (otherwise, it would be an ion). You can then use that information to guess at some of the properties of the element.

Some periodic tables include more information, but that's about it.
It provides a)Atomic Nbr(Nbr of Protons, top left corner), b) Symbol for te element(in the Centre in bold) & c) The Mass Nbr, also called Atomic weight, which is the ttl amt of subatomic particles in the nucleus(Right bottom corner).
Each box displays a chemical element symbol along with its atomic number. Some versions of the table list atomic mass as well.

Answer 2

One short list is: The symbol of the element (which leads to its Latinized name), how much a mole of the stuff weighs, how many protons (and neutrons, with a quick calculation) are in its nucleus, how many electrons are orbiting it, how many types of ions each one usually makes, whether it is a metal or gas or other, a good guess as to their atomic radius, electronegativity, whether their valence shells are full or not (which determines to a great extent how reactive they are). much more information is in the link below.

Answer 3

The Group that the element belongs to will have common characteristics, such as being metals or nonmetals. All of the elements in a group have the same electron configuration in their outermost energy levels. This electron configuration will indicate how that element will react with other elements, such as forming ionic or covalent bonds, including how many electrons will be lost or gained in an ionic bond, or how many electrons will be shared in a covalent bond. There are also trends down a group or left to right across a period. For example, the atomic radius increases down a group from top to bottom, while atomic radius decreases from left to right across a period.

Answer 4

We can find the period, the group (and the general properties in this group), atomic number, atomic weight, chemical symbol, etc.

Answer 5

It can not. The table is just a organized way to write the elements.

Answer 6

by comparing atoms
