they are determined by the outermost shell of electrons
The same way anything in science is determined: experiment, trial and error.
by the atomic number and the number of valence electrons
The periodic table is organised in order of increasing atomic number so that their properties could be determined in same rows and columns
The elements with similar properties are placed in groups. Periodic table contain 18 groups.
One can recognize a periodic trend on the periodic table by observing properties of different elements from the left side to the right side of the periodic table.
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
Physical properties like lustre cannot be determined. Chemical properties like enthalpy values is hard to determine.
The periodic table is organised in order of increasing atomic number so that their properties could be determined in same rows and columns
Various chemical properties can be determined. It is done by estimation from position of element.
the periodic table of elements In this table, elements having similar chemical properties are stacked up. The chemical properties are determined by how many free bonds an atom has open, which is related to how many electrons are in that element's outer shell.
Groups on the periodic table with similar properties are called families.
The physical properties are not listed in periodic table. The properties like density is not listed.These can't be found on periodic table.
Periodic table group elements with same properties together. Hence their properties can be identified.
Position of Periodic Table describes chemical properties. it is estimated from its position in table.
Reactivity is associated with position. Chemical properties of element can be determined from its position.
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
There is no group p on the periodic table.
D. location on the periodic table
