The elements are arranged in increasing ATOMIC NUMBER.
NOTE ; NOT Atomic Mass.
The atomic Number = Number of protons = the number of electrons in the neutral atom.
NB A different number of protons is a different element.

What are III group elements in periodic table?
Group III elements in the periodic table are boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). They are metallic elements with varying properties, such as being good conductors of electricity and having low melting points. These elements are commonly used in a variety of applications, from electronics to alloys.
Silicon is in this period?
Period 3. In the periodic table of elements you can decipher which period does an element belong by looking by the number of ROWS and which number is your element included in.
What are the first rows of transition metals at the bottom of the periodic table?
The first rows of transition metals at the bottom of the periodic table are typically the actinides and lanthanides. These elements are located in the f-block of the periodic table and have partially filled d orbitals. They are known for their unique properties and are commonly used in various applications such as nuclear energy and magnet production.
Which element is 45 on the periodic table of chemical elements?
Element 45 on the periodic table is rhodium, which has the symbol Rh. Rhodium is a rare transition metal that is commonly used in catalytic converters, jewelry, and electroplating.
Which elements of the periodic table of elements are solids or liquids and which are gases?
Elements on the far left side of the periodic table are very active solids.Since these elements only have one valance electron they bond easily with almost any other element in the periodic table. Hydrogen is the exception because it has one electron and one proton so it bonds easily but it's not a solid... Really, as you move from the left to the right on the periodic table the elements get less reactive to the point where they do not react to anything at all. The Alkaline Earth Metals1 are the extreme bonding examples while all the way on the other side the Noble Gases, having eight valance electrons, are complete without any bonding. The reason that the elements on the left side of the periodic table are active is because they have low numbers of valance electrons2. The 'goal' of any chemical bond is to have the atoms involved end up with eight valance electrons and become completely stable.________________________________________________________________________ 1. Alkaline Earth Metals are the most reactive of the elements and are located on the far left of the periodic table. 2. Valance electrons are electrons that are on the far outside of an atom and are used in chemical bonding.--Byoen
What is the periodic table of elements used for?
The "Periodic Table of Elements" is used for classifying the elements, and to know which one is which.
What are some commonly used compounds on the periodic table?
There are NO compounds in the Periodic Table. They are all Elements.
What is used to order elements on a periodic table?
Elements on a periodic table are ordered based on their atomic number, which represents the number of protons in the nucleus of an atom. This yields a unique and systematic arrangement of elements according to their properties.
In what order did Mendeleev arrange the elements in the first periodic table?
Mendeleev arranged the elements in the periodic table according to their atomic masses.
What property is used to determine the order of the elements on the modern periodic table?
The atomic number is used to determine the order of the elements on the modern periodic table. The atomic number represents the number of protons in the nucleus of an atom, which defines the element. Elements are arranged on the periodic table in order of increasing atomic number.
On the periodic table of elements which abbreviation is used to represent gold?
The answer is: Au
How is an atom used to create a periodic table?
The elements are arranged in the increasing order of their atomic number.
What was used by Mendeleev to organize his periodic table?
He organised the elements in the increasing order of the atomic mass.
What on the periodic table is an element?
Everything on The Periodic Table is an element, hence the the name PERIODIC TABLE OF ELEMENTS - - - - - Well...the paper the table is printed on and the ink used to print it with are not elements, but everything else is.
What did Dmitri Mendeleev discover?
he drew up a table that grouped elements according to their atomic weights, his table became the basis for the periodic table of elements used today.
What was the first attempt of listing elements on the periodic table?
The first attempt at listing elements on the periodic table was made by Dmitri Mendeleev in 1869. He arranged the elements in order of increasing atomic weight and grouped elements with similar properties together. Mendeleev's periodic table laid the foundation for the modern periodic table used today.
What do you call the table used to group atoms?
The Periodic Table of Elements
