What are the elements in the second period of the periodic table of elements?
You can discover this by looking at a periodic table of the elements.The rows of the table are called periods; the columns are called groups.The second period therefore begins with the element Lithium and ends with the element Neon.
How were the elements arranged on his periodic table?
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
Why is the arrangement of electrons in an element key to understanding why each element behaves the way it does?
The elements in the periodic table are arranged based on how reactive they are, which is based on how many electrons they have in their outer shell. For example, the elements on the ends are very reactive because on one side the elements have seven electrons and on the other the elements have one. The elements with one electron are trying to get rid of their electron whereas the elements with seven electrons are trying to find another to make their shell complete, as there are eight electrons in the outer shell of an electron shell.
In what way is the table of the elements periodic?
The Periodic Table is arranged in periods and groups; elements are placed in the ascending order of the atomic number. The law of periodicity from Mendeleev is respected.
A representative element with eight electrons in its valence shell is said to be at .?
This is a noble gas (group 18 of the periodic table); the valence shell is completsly filled.
108 E in the P T?
That stands for "One hundred eight Elements in the Periodic Table", but this is now obsolete. As of 2008, at least 117 elements have been discovered.
How many elements are there in 3rd transion elements?
There are eight third period transition elements on the periodic table.
What are the elements in the second period of the periodic table of elements?
You can discover this by looking at a periodic table of the elements.The rows of the table are called periods; the columns are called groups.The second period therefore begins with the element Lithium and ends with the element Neon.
How did New lands help the periodic table of elements?
arranged the elements in increasing order of their atomic weights. Elements were arranged in a group of eight. Properties of every element was found to be a repeatation of the first element. It was discarded because it failed to leave spaces for undiscovered elements. The prediction hold true for light metals but not for heavy metals.
How were the elements arranged on his periodic table?
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
What are the eight element?
the eight elements are ethics,integrity,trust,training,teamwork,leadership,recogninition,communication. i think those are the eight elements.
What is the group of elements in periodic table with eight electrons?
group 18, noble gases
Why does an element gain or lose electrons to become an ion?
When elements react with other elements, they gain or loose electrons. Electrons are the reason that some elements react and others do not. Each element wants to have eight outer electrons. This is called the octet rule. (oct means eight). However, most elements do not have eight (except for the elements in the 18th column of the periodic table). The periodic table shows how many electrons each element has on its outer-layer. The last number of the column # (in the periodic table) is the number of electrons that the element contains in its outer-ring. For example, elements in the first column have one. Another way is when substances burn and reach oxygen. This is called oxidation reaction.
What does period mean in the periodic table?
Periodic means repeating. When Mendeleev was rearranging the elements, he noticed that some of their properties matched with one another about every eight elements. Thus, when the elements are arranged in the rows of the Periodic Table, they also have matching properties in each column.
What are the similarities between the Law of Octaves and the Periodic Table?
The properties of elements in the periodic table are repeated at intervals of eight atomic numbers.Unfortunately, in music word "octave" refers to the scale between the first and eighth note - second note is seven notes after the first. In the periodic table, the pattern repeats after a gap of eight elements.
What is the common name for the elements that make up group eight-teen of the periodic table?
the Noble Gases
What contains eight elements?
Element 1 is hydrogen; element 8 is oxygen. Thus water, H2O, is such a substance. Another less familiar one is hydrogen peroxide, H2O2.
