How are the trends in the periodic table helpful in identifying an element?
The periodic trends that arise from the arrangement of the periodic table provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or period and the periodic nature of the elements.
On the Periodic Table of elements What is a period?
The periods of The Periodic Table is shown in the column to the left of the elements. It represents the number of "shells" or "layers" of electrons that the particular element contains.There are a total of 7 periods including the Lantanoids anf the Actinoids
Why do you need a periodic table?
As new elements are "discovered" or created artificially, the discoverer/creator gets to name them (within limits). So recent artificially-created elements have been named things like berkelium (named for the University of California at Berkeley, where it was synthesized) or mendelevium, named after Dmitri Mendeleev, father of the Periodic Table. According to www.webelements.com, we're up to element 111, roentgenium, which was discovered on 8th December 1994 at the GSI in Darmstadt, Germany.
What of the periodic table is oil made of?
Oil is a mixture of compounds (2 or more elements bonded together), not an element itself, so it does not appear in the periodic table. Crude oil is a mixture of Hydrogen and Carbon compounds (hydrocarbons) of varying lengths, but with the general formula CnH2n+2, for example octane, C8H18. The different compounds within the oil are separated by fractional distillation before it is suitable for use.
You are on the nuvaring birth control you have only had it in for four days but you have had your period within those days Is it possible for you to get pregnant since you have had sex for three days.?
good new is you had your period meaning you are not pregnant.
In the periodic table what is a period?
A period on the periodic table is a row.This is the horizontal section of the periodic table.
Period number of manganese?
Manganese is in the fourth period of the Periodic Table of Elements. Periods are rows, groups are columns within the Periodic Table of Elements.
What does a period on the periodic table tell us?
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
A horizontal row of elements on the periodic table is called?
The horizontal rows of the periodic table are called Periods and the vertical rows are called groups.
How are families within the periodic table similar?
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.
What is the relationship between a period and a group in the periodic table?
A period in the periodic table refers to a horizontal row of elements that have the same number of electron shells. A group, on the other hand, refers to a vertical column of elements that have similar chemical properties due to having the same number of valence electrons. So, elements within the same period do not have similar properties, but elements within the same group do.
What is the group of 17 elements is called?
A group of 17 elements is called a period in the periodic table. This period corresponds to the number of electron shells in an atom within that group. Elements in the same period have the same number of electron shells.
Why do elements within a period of the periodic table have different properties?
They have different numbers of valance electrons...
Within each period in the periodic table elements have similar properties because they have the same number of valence electrons?
Yes, elements within the same period of the periodic table have the same number of electron shells, which determines their chemical properties. Elements in the same period also have the same number of energy levels and are influenced by similar trends in atomic radius and electronegativity due to the reactivity of their valence electrons.
What can the period of a element be determined by?
The period of an element in the periodic table can be determined by the number of electron shells or energy levels that the element's atoms have. Each period on the periodic table corresponds to the number of electron shells occupied by the elements within that period.
Horizontal row in the periodic table?
A horizontal row in the periodic table is called a period. There are seven periods in the periodic table, labeled from 1 to 7. Each period represents the energy levels of the elements within that row.
Why is a row in a periodic table called a period?
A row in the periodic table is called a period because elements within the same row have similar chemical properties which repeat in a periodic manner. As you move across a period, the number of protons and electrons increases, leading to similar trends in the elements' properties.
