What information does the periodic table include?

The most basic periodic table includes the names and symbols of all of the elements, and their atomic numbers and atomic weights. It also includes group numbers and period numbers.


What do the numbers mean in a periodic table?

Depends on what version you are looking at. The integers going from 1 to around 100 are the atomic numbers of the elements and these are the numbers of protons (= numbers of electrons) in the atom. Numbers which run from 1 to around 250 and are integers are the atomic weights of isotopes, and numbers which are not integers are atomic weights of elements found in nature, which are mixtures of isiotopes.


Where can you found the symbols for elements?

A periodic table is a chart with all of the elements and their symbols, their atomic numbers and atomic masses. Good ones will also have the name of the element to make finding them easier.


What are symbols and numbers that tell what elements are in a compound and what there ratios are?

Atomic symbols combined with subscript numbers in a chemical formula tell what elemtnsare in a compound and what the ratios between atoms of these elements are.


What is the relationship between an elements isotopes and the elements atomic mass?

Each isotope of an element has an atomic mass. The average of all the atomic masses of an element's isotopes gives an elements atomic weight. For this reason, atomic weights are decimal numbers.


Why is the periodic table arranged in order atomic weight?

The present periodic table is arranged in order of increasing atomic numbers not the atomic weights , before modern periodic law the elements were arranged on the basis of atomic weights.


What does the periodic table of elements contain?

The periodic table contains all of the known elements, which are arranged according to increasing atomic number (number of protons). The most basic periodic table includes the element names and symbols, their atomic numbers, and their atomic weights. The elements are arranged in 18 groups/families according to similarities in their electron configurations.


Is it possible for the atoms of different elements to have the same mass numbers?

Yes, there are elements which have isotopes, i.e same atomic number & different atomic weight, so atoms f different elements can have same atomic weights.


The elements in the periodic table goes accoring to?

In the modern form of periodic table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.


Why do some elements have their atomic weights in parentheses in the periodic table?

Elements with their atomic weights enclosed in parenthesis is usually because they have no stable isotope.


What data about elements are found on the Periodic Table?

On standard ones, Their Symbols, atomic & mass numbers, and groups.


Does the periodic table gives the mass number of the most common isotopes of an element?

The periodic table give the atomic numbers and the atomic weights of chemical elements.


Who assigned atomic numbers to elements?

Moseley was the person to assign atomic numbers to elements!


What p is a table that lists the symbols of chemical elements and there atomic numbers?

Tough question to decipher, but here is a link. I .


Why do some elements have their atomic weights in parentheses?

Elements that have their atomic weights in parentheses are unstable and radioactive, some of these will decay in less than a second. The atomic mass in the parentheses is the most stable isotope of the element.


Why the elements in the peridic table rarely have whole numbers?

If you think to atomic weights:1. First cause: the atomic weight is the sum of the weights of protons, neutrons ans electrons.; they don't have masses as integers.2. Second cause: also occurs the so-called mass defect (binding energy).Not atomic mass for elements; atomic weight is correct.


What are the abbreviations of the elements called?

The abbreviations of the elements are called atomic symbols.


Atoms that have the same atomic numbers but different atomic weights are called what?

Isotopes.


What elements have atomic number?

All chemical elements have atomic numbers.


How are the actinide series elements created?

Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.


How did they come up with the symbols for atomic mass and atomic number?

There are no symbols for atomic mass and number. They're just written as numbers.


Why are some of the atomic weights on the periodic table whole numbers within parenthesis?

The parentheses indicate that those elements have no stable isotopes, which basically means that those elements are radioactive.


True or false relative mass is a system of comparing atomic masses to carbon?

True. The unit for the atomic weights of chemical elements is the relative atomic mass unit (1/12 from the atomic mass of the isotope 12C). Note that atomic weights is used for elements and atomic mass for isotopes.


What was the periodic table first arranged by. How has this changed?

In 1869 Russian teacher and scientist Dmitri Mendeleev, presented a periodic table of the elements based on atomic weights. The current periodic table is arranged by the atomic numbers of the elements.


Where is the atomic number located on the periodic table?

There is no standard position. In the online version produced by the Royal Society of Chemistry, it is underneath the elements' symbols. The Wikipedia table shows atomic numbers above the symbols. So take your pick!
