What are the first ten element of the periodic table?
What Are the First 20 Elements?
- Element Symbols and Numbers. The number of the element is its atomic number, which is the number of protons in each atom of that element.
- Chemical Elements. To be an element, a substance has to at least have protons, since these particles define the type of element.

Can identify the four blocks of the periodic table?
There are 4 blocks in the periodic table. The blocks are: s-block. p-block. d-block. f-block. All the elements in a block are very similar but each one is slightly different than the other. All of the s-block elements are metals. Generally they are shiny, silvery, good conductors of heat and electricity, and lose their valence electrons easily.
What do columns on the periodic table tell you?
Vocabulary
- Group (family): A vertical column in the periodic table.
- Alkali metals: Group 1A of the periodic table.
- Alkaline earth metals: Group 2A of the periodic table.
- Halogens: Group 7A of the periodic table.
- Noble gases: Group 8A of the periodic table.
- Transition elements: Groups 3 to 12 of the periodic table.
What is the last column of the periodic table called?
PERIODS
- DECREASING SIZE. As you go across a period, the atoms get slightly heavier, but they also get smaller. ...
- PHOSPHORUS MATCH. Phosphorus is a non-metal element. It is a yellowish, waxy, slightly see-through solid. ...
- UNREACTIVE ARGON. Argon is very unreactive and does not combine with other elements. In arc welding, metals are melted surrounded by argon gas.
What do the first 2 columns on the periodic table have in common?
Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.
What are the first column of the periodic table called?
Alkali MetalsAlkali Metals: Facts About the Elements on the First Column of the Periodic Table. There are alkali metals all around you right now. Sodium is found in table salt, lithium in your phone battery and potassium in your bananas. Alkali metals make up six different elements found in the first column of the periodic table.Jan 5, 2021
What are the two columns on the periodic table called?
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.Jun 5, 2019
What are the columns of the periodic table?
The columns, or groups, on the periodic table represent the atomic elements that have the same number of valence electrons, or those electrons in the outermost orbital shell.Jan 5, 2022
What is the third column of the periodic table called?
The elements can also be classified into the main-group elements (or representative elements) in the columns labeled 1, 2, and 13–18; the transition metals in the columns labeled 3–12; and inner transition metals in the two rows at the bottom of the table (the top-row elements are called lanthanides and the bottom-row ...
What is the second to last column of the periodic table called?
Group Names: The elements in the second to last column (group) of the Periodic Table are called Halogens. The elements in the last group (column) of the Periodic Table are called Noble Gases.
What are the vertical columns of the periodic table called?
The horizontal rows are called periods and the vertical columns are called groups. Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency. An example of a group in the periodic table is the alkali metal group.
What are the 18 columns of the periodic table called?
Each of these rows are called periods. The vertical columns of elements are called groups, or families.Jul 15, 2021
What are the horizontal columns of the periodic table called?
The horizontal rows are known as periods and vertical columns in the periodic table are known as groups.
How many columns are in the periodic table?
18There are 18 vertical columns in the modern periodic table which are known as groups.
What are the rows and columns called in the periodic table?
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 is another name for a column of elements?
In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.
What are the columns and rows in the periodic table called?
As with any grid, the periodic table has rows running left to right, and columns running up and down. The rows are called PERIODS and the columns are called GROUPS .
What is each column called?
Each column is called a group . The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.
How many rows are there in the periodic table?
The Periodic Table: Families and Periods. In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. What is the second column of the periodic table called?
Which column of the periodic table contains alkaline earth metals?
The second column of the periodic table is the alkaline earth metals: beryllium, Be; magnesium, Mg; calcium, Ca; strontium, Sr; barium, Ba; and radium, Ra. These metals have similar properties to alkali metals except they are harder, have higher melting points and densities, and react more slowly with oxygen and water.
What are the two ways to categorize elements in the periodic table?
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.
