What is the first row of the periodic table?
(Look at the periodic table.) Each row holds a different number of elements. The first row has two elements—hydrogen and helium. The next two rows have eight elements each.
What are the rows of the periodic table called?
The horizontal rows on the periodic table are called periods, where each period number indicates the number of orbitals for the elements in that row, according to Los Alamos National Laboratory (opens in new tab).
What is the top row of the periodic table?
You've got Your Periods… When you look at the periodic table, each row is called a period (Get it? Like PERIODic table.). All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons.
What is the first column of the periodic table called?
Alkali metals: The alkali metals make up most of Group 1, the table's first column. Shiny and soft enough to cut with a knife, these metals start with lithium (Li) and end with francium (Fr).
What are horizontal rows in the periodic table called?
The columns of the periodic table are called groups. Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods.
What is group 1 in the periodic table?
Group 1 elements include the alkali metals, Li, Na, K, Rb, Cs, Fr. The alkali metals are all soft, shiny and metallic when cut. They react easily with water, have low melting points and densities, and are good conductors of electricity. They all have one valence electron that they lose easily to form ions.
What are the horizontal rows called?
period The horizontal rows are called period and the vertical columns are called groups.
What is the row and column?
The key difference between columns and rows is that a column arranges data vertically from top to bottom, while a row arranges data horizontally from left to right. Rows and columns are different based on how they align data. Rows and columns are common concepts in computer science and data analytics.
What are the 7 rows on the periodic table?
The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups. Groups are labeled at the top of each column.
What is the second row of the periodic table called?
The elements in group 2 (the second column) form compounds consisting of one atom of the element and two atoms of hydrogen: These are called alkaline earth metals, with similar properties among members of that group.
What are rows and columns in periodic table?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
What are periodic table columns called?
The table is divided into four roughly rectangular areas called blocks. The rows of the table are called periods, and the columns are called groups. Elements from the same column group of the periodic table show similar chemical characteristics.
What are the bottom 2 rows of the periodic table called?
The two rows of 14 elements at the bottom of the periodic table are the lanthanides and the actinides, whose positions in the periodic table are indicated in group 3.
What is group 1 called?
The alkali metals The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is Group 2 called?
Table of contents No headers. The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.
What is vertical row or column?
The row is an order in which people, objects or figures are placed alongside or in a straight line. A vertical division of facts, figures or any other details based on category, is called column. Rows go across, i.e. from left to right. On the contrary, Columns are arranged from up to down.
Where is row and column?
Each row is identified by a number. For example, the first row has an index 1, the second – 2 and the last – 1048576. Similarly, a column is a group of cells that are vertically stacked and appear on the same vertical line.
What are rows and periods on the periodic table?
A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.
What are rows and columns in the periodic table?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
What are the 5 parts of the periodic table?

What is horizontal row?
What Are Horizontal Rows? Horizontal rows are a calisthenic exercise that primarily target your latissimus dorsi, considered one of the largest muscles found in our body. Your lats are located on the upper lower back and even extend near the side of your waist area.
Are periods rows or columns?
This arrangement is called the periodic table. The columns of the periodic table are called groups. Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods.
How many rows are there in periodic table?
Answer: there are 7 horizontal rows which are known as periods . And 18 vertical columns.
What is in group 1 of the periodic table?
Group 1 elements include the alkali metals, Li, Na, K, Rb, Cs, Fr. The alkali metals are all soft, shiny and metallic when cut. They react easily with water, have low melting points and densities, and are good conductors of electricity. They all have one valence electron that they lose easily to form ions.
What is Group 3 called?
Group 3 is the first group of transition metals in the periodic table.
What is row and column in periodic table?
The rows are called PERIODS and the columns are called GROUPS.
Whats a row and column?
The key difference between columns and rows is that a column arranges data vertically from top to bottom, while a row arranges data horizontally from left to right. Rows and columns are different based on how they align data. Rows and columns are common concepts in computer science and data analytics.

What are the sections of the periodic table called?
The periodic table has three main regions—metals on the left, nonmetals (except hydrogen) on the right, and metalloids in between. The peri- odic table on pages 20 and 21 indicates these regions with different colors.
