In some reactions, one of the products of the two reactions may be common(means that for example you can get a same product by using two different chemical reaction).
Simplest example ever(given to grade 6 kids) :
-NaOH + HCl ----> NaCl (Salt) + H2O (Stomach inflamation base displacement with stomach acid)
-H2CO3 -----> H2O + CO2 (Hydrogen Carbonate acid decomposes to water and carbon dixide)
You can get water by using both reactions.
(Ofcourse getting water isn't the purpose) :)
Be, Mg, Sr
which Be means beryllium
which Mg means magnesium
which Sr means strontium
Each group on the Periodic Table shares similar properties with one another. Example: all of the halogens, F, Cl, Br, I, As need 1 electron to complete their out energy level.
If they are in the same column of the periodic table they will react similarly because they have the same number of valence electrons.
The columns or groups. One example is the alkali metals.
The groupings on the periodic table that have similar chemical properties/react similarly are called GROUPS and are the vertical columns numbered 1 - 18.
The groups of the periodic table (its columns).
barium and magnesium
O, S, Te
Yes it actully does
The elements in group 18 are not relatively inert but it is not true to say that they do not react.
because it does not react with other elements
group 1 elements.
the periodic table contains the 118 base elements, these react to form a varity of compounds methane is a compound produced when four hydrogen atoms and a carbon atom react
every column on the table represents a family that react similarly with other elements.
periodic table
the periodic table
elements are in the same group since they react similarly to other elements in that group.
Yes it actully does
The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.
Noble gases or group 18 elements
The elements in group 18 are not relatively inert but it is not true to say that they do not react.
because it does not react with other elements
Groups on the Periodic Table run vertically. Each group has the same number of valence electrons in its outer shell, meaning that each will react similarly to the other elements.
Elements in the Periodic Table that are not reactive are called the Noble Gases.
Potassium would strongly react with the elements in group 17 and group 16.
