What else can I help you with?
A period is a horizontal on the periodic table true or false?
Yes!The elements are arranged in horizontal rows and vertical columns to represent what is called the periods on the periodic table.
What are the horiontal columns or families or groups in the periodic table?
The columns on The Periodic Table are called groups. All elements in the same group share characteristics such as reactivity toward other substances. Also, elements in the same group contain the same amount of electrons in the outer shell of their atoms.
What is the difference between periods and families?
Periods refer to the rows on the periodic table, which indicate the number of electron shells an element's atoms possess. Families (or groups) refer to the columns on the periodic table, which indicate elements with similar chemical properties due to having the same number of valence electrons.
What is a period on the periodical chart?
A period on the periodic table is a horizontal row that categorizes elements based on the number of electron shells they have. Each period corresponds to the number of electron shells an element's atoms possess.
Are columns of elements called periods?
No, columns of elements in the periodic table are called groups or families. Periods are the rows of elements that run horizontally across the table. Each period corresponds to the number of electron shells an element's atoms have.
What is the term for a group of atoms?
If the group of atoms are all the same, it is called a molecule. If the group of atoms are different, it is called a compound, assuming they are bonded in some way. Otherwise, it is just called a group of atoms.
What are the columns of the periodic table of elements?
f-block columns
Horizontal rows on Periodic Table?
Horizontal rows on the Periodic Table are called periods. Each period represents a specific energy level of the elements within it, with the number of the period corresponding to the number of electron shells in the atoms of the elements. The first period consists of only two elements (hydrogen and helium) as they have electrons in the first energy level, while the subsequent periods expand as more electron shells are filled.
What is a group or family on the periodic table?
The alkali and alkaline earth and transitions are all groups of the periodic table ANOTHER POINT OF VIEW: A group or family is the vertical columns on The Periodic Table of the Elements.
What are columns on the periodic table orginized by?
The columns tell you how many electrons the atoms have in their outer shells, which is a very essential information to understand reactions. Group 1 has 1 electron in the outer shell, group 2 has 2 electrons, etc.
What do the horizontal rows on the periodic table represent?
Whereas the vertical columns on the periodic table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
What is a row in a the periodic table called?
A row of the periodic table is known as a period.Related Information:Across a period, you can see how the electrons fill the energy levels from the s sub-level to the p sub-level. The highest-filled energy levels correspond to the row, or period, number. Down a group, you can see how many valence electrons are present in the atoms of each element.
