What Is The Periodic Table?
The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic quantity, hydrogen, to the element with the highest atomic number, oganesson. The atomic number of an element is the number of protons in the nucleus of an atom of that element. Hydrogen has 1 proton, and oganesson has 118.
What is the name of the columns of elements on the periodic table?
Groups
What is the symbol for calcium on the periodic table?
CA
Why Is The Perioic Table So Important?
The periodic table of elements puts all the known elements into groups with similar properties. This makes it an important tool for chemists, nanotechnologists and other scientists. If you get to understand the periodic table, and learn to use it, you'll be able to predict how chemicals will behave.
Which Element is NA?

How are the elements of a period arranged in the modern periodic table, from left to right?
In order of increasing atomic number
What Is Mass?
Mass is the amount of matter or substance that makes up an object. It is measured in units called kilograms, which can be abbreviated kg. Mass always stays the same, while weight changes with changes in gravity.
Who invented the periodic table?
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern-day periodic desk, leaving gaps for elements that were yet to be observed. at the same time as arranging the elements according to their atomic weight, if he observed that they did no longer fit into the group he could rearrange them
What is an Element?
An element is a substance which cannot be spilt up into two or simpler substances by the means of chemical methods of applying heat, light or electric energy.
For Example: - Hydrogen is an element which cannot be split into two or more simpler substances.
Potassium

In your own words what is the Periodic table?
The periodic table is a chart where elements are arranged according to the increasing number of electrons they possess. The number of electrons in the outer shell allows them to be placed in groups and is used to predict their chemical behaviour.
Which element is in group 2 and period 3 of the periodic table?
Magnesium (Mg)
In your explaintion what do you think is a atom?
Atoms are the smallest building blocks of matter and make up everything around us. Every atom has a center called a nucleus, which is made of particles called protons and neutrons. Electrons move in electron shells around the nucleus. Atoms can bond to one another to form solids, liquids, or gases.
Also known As an A Proton Number?
Atomic Number
What are the 3 main groups of the periodic table?
The three major groups on the Periodic Table are the metals, nonmetals and metalloids.
How many periods or rows are there on the periodic table?
7
