The elements are arranged by how many protons or electrons are free or available for interaction with other elements. For instance, sodium is in the first column, with one proton available or a +1 charge, Calcium in the second column with a +2 charge etc. From the right side Chlorine is a -1 charge etc. This is a simplified answer, but you should get the idea.

Is the structure of the periodic table based on the placement of electrons?
Yes, the structure of the periodic table is based on the arrangement of electrons in an atom. Elements are organized by increasing atomic number, which corresponds to the number of protons and, typically, electrons in a neutral atom. The table's rows (periods) reflect the number of electron shells, while the columns (groups) indicate similar valence electron configurations, influencing the elements' chemical properties. This electron configuration is fundamental to understanding the behavior and reactivity of the elements.
What is the periodic tables orderly arrangement of?
The periodic table is an orderly arrangement of elements based on their atomic number, electron configuration, and chemical properties. It organizes elements into groups and periods to show trends in their behavior and properties.
Will atomic properties vary in a similar way in a different periods?
The atomic properties depends on the electrons of the outer shell. THe elements in differnent periods have the same arrangments of electrons in the outer shell. Thus, atomic prperties vary in a similar way in diffrent periods
What is the scientific term used for columns and rows on the periodic table?
The scientific term for columns on the periodic table is "groups" or "families," while the term for rows is "periods." Groups contain elements with similar chemical properties, while periods indicate the energy levels of the electrons in the atoms. The arrangement reflects the periodic law, which states that elements exhibit periodic trends in their properties when organized by increasing atomic number.
What are called periods on the periodic table of elements?
Groups or families; all are arranged by the number of valence electrons.
Is the structure of the periodic table based on the placement of electrons?

This electron configuration is fundamental to understanding the behavior and reactivity of the elements.
Why some of the periods have different numbers of elements?
The early periods have less elements because they are filling up energy levels which hold only a few electrons. The later periods contain elements with electrons in levels with a greater capacity.
How are properties determined on the periodic table?
Properties of elements on the periodic table are determined by their atomic structure, specifically the number of protons, neutrons, and electrons they possess. These properties include atomic number, atomic mass, reactivity, conductivity, and others. The arrangement of elements into rows (periods) and columns (groups) on the periodic table is based on similarities in their properties.
What are periods and groups?
Elements in the periodic table are arranged in periods (rows) and groups (columns). Atomic number increases as you move across a row or period. The period number of an element signifies the highest unexcited energy level for an electron in that element. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement. The outer electrons are called valence electrons.
What periods contain elements with electrons in s'p'dand f orbitals?
It is C. i got lucky when i guess:)
How are periods in the periodic table similar?
The elements in a given period have the same number of core electrons.
What is the periodic tables orderly arrangement of?
The periodic table is an orderly arrangement of elements based on their atomic number, electron configuration, and chemical properties. It organizes elements into groups and periods to show trends in their behavior and properties.
What separates elements into different periods?
The periods on the periodic table separate the elements according to which shell their valence electrons fall into. So, elements located in the third period will have the sum of all electrons contained in that period. For example: P has an electron configuration of 1s2, 2s2, 2p6, 3s2, 3p3 ......................sooo, add up all electrons from the third shell (3s2 & 3p3) to get the total number of valence electrons of the element.
How many electrons are contained in completed outer shells for all periods above period one?
For all periods above period one, the maximum number of electrons that can be contained in the completed outer shell is eight. This is known as the octet rule, observed in periods 2 and beyond due to the arrangement of electrons in shells and subshells according to the periodic table.
Will atomic properties vary in a similar way in a different periods?
The atomic properties depends on the electrons of the outer shell. THe elements in differnent periods have the same arrangments of electrons in the outer shell. Thus, atomic prperties vary in a similar way in diffrent periods
O The periodic table of elements is the arrangement of elements according to?
The periodic table of elements is arranged according to atomic number, which is the number of protons in an atom's nucleus. Elements are organized in rows (periods) and columns (groups) based on their similar chemical properties and electronic configurations. This arrangement allows scientists to predict an element's behavior and properties.
What are the different rows of elements in the periodic table called?
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.
