Why are valence electrons important?
The reason for this is that the valence electrons, which are the electrons in the outermost shell, are the ones taking part in chemical reactions. These electrons are either donating, accepting, or sharing. Moreover, the more filled the valence shell is, the more stable the element.
What are noble gases?
The noble gases, also called aerogens, are inert gases. Some examples include argon, krypton, and neon. They can be found in group eighteen on the periodic table. Likewise, this means they have a complete valence shell. For this reason, they are stable and relatively unreactive.
What is the name of the group of elements that are found in the three states of matter at standard temperature?
The name halogen means “salt formers” in greek. This is evident in nature as halogens interact with metals to form various salts. On another note, the halogens are a unique group of elements. They are the only periodic family that contains elements in the three states of matter at standard temperature. There are 6 halogens and they are located in group 17. These elements include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are highly reactive, highly electronegative, and highly toxic non-metals.
Which metals are the second most reactive?
The alkaline earth metals are the second most reactive family on the periodic table (following behind the alkali metals). Moreover, they are strong reducing agents which means they donate electrons in chemical reactions. They are also good thermal and electrical conductors.
How are elements organized in the periodic table?
The periodic table is organized into groups (vertical columns), periods (horizontal rows), and families (groups of elements that are similar). Elements in the same group have the same number of valence electrons. Meanwhile, elements in the same period have the same number of occupied electron shells. In 1869 Russian chemist Dmitri Mendeleev noticed there existed an innate pattern of organization for the chemical elements. From this deduction, he formed the periodic table. It is important to note how the location of elements on this table tells us about their properties. A quick way to understand an element’s chemical and physical properties is to know the periodic trends. These trends tell you where the highest and lowest types of properties are concentrated on the periodic table. For a more in-depth explanation of periodic trends, click here.

How does the atomic number of a component tell you how many protons are in the core?
The atomic number of the component tells you how many protons are in the core, and the number of electrons around it. With oxygen, that tells you that every molecule has eight positive protons at its focal point, and eight negative hardware transmits it. Each component on the intermittent table has an atomic number that exits it. Apart from the fact that it lets you check for protons and electrons, it likewise decides the location of the component on the table.
What is each row of the periodic table called?
Each row is a period. Each row of the periodic table is called a period . Elements have the same atomic number in each period, which is where the electrons go. The number of periods is the same as the number of orbitals. If in any table have 2 rows then also have 2 periods.

Why is the periodic table given a range?
When a range is given, it's because the abundance of isotopes varies from one sampling location to another.
What is the atomic number of an element?
The atomic number is how many protons an atom of that element contains. The number of protons is the deciding factor when distinguishing one element from another. Variation in the number of electrons or neutrons does not change the type of element.
What are the vertical columns in the periodic table called?
Mendeleev's original periodic table organized elements in order of increasing atomic mass or weight. The vertical columns are called groups. Each element in a group has the same number of valence electrons and typically behave in a similar manner when bonding with other elements. The horizontal rows are called periods.
What happens when the number of electrons changes?
Changing number of electrons produces ions while changing the number of neutrons produces isotopes . The element's atomic mass in atomic mass units is a weighted average mass of the element's isotopes. Sometimes a periodic table cites a single value for atomic weight.
What is the valence of all elements in the first column?
For example, all of the elements in the first column are reactive metals that have a valence of +1. All elements in a row have the same outermost electron shell. A good periodic table is a great tool for solving chemistry problems. You can use an online periodic table or print your own.

Can periodic table games be used for grade?
The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.
Did Mendeleev's predictions get dismissed?
There were plenty of skeptics and it took years to gain international acceptance, but once newly-discovered elements matched the ones that Mendeleev predicted, his patterns could not be dismissed. In addition, some of the properties that he "fudged" were later recalculated and found to be much closer to his predictions.
