The atomic number of an element shows the number of protons that element has. Changing the number of neutrons creates a new isotope, and changing the number of electrons creates an ion. But changing the number of protons creates a different element.

What is the basis of arranging the elements in the periodic table?
increasing atomic number and repeating properties
How can you predict the properties of missing elements?
yes, properties of an element depends on its atomic number and atomic mass unless it is an exception and the atomic number and atomic mass of unknown elements are known by placing it in periodic table
What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
Has similar properties with elements T but has lower atomic number?
flourine
What is the periodic law?
Periodic Table of elements.
What is the basis of arranging the elements in the periodic table?
increasing atomic number and repeating properties
The periodic law states that the properties of elements will repeat when the elements are arranged by _______.?
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
How can you predict the properties of missing elements?
yes, properties of an element depends on its atomic number and atomic mass unless it is an exception and the atomic number and atomic mass of unknown elements are known by placing it in periodic table
What determines the properties of elements?
the properties of elements are determined by the structures of their atoms.
How do you distinguish elements?
Elements are distinguished by their atomic number, which is the number of protons in the nucleus of an atom. The element's atomic number determines its chemical properties.
What two properties are the modern periodic table based on?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
Why has the periodic able set out the way it is?
All the elements have unique atomic number. The properties of elements are periodic after certain atomic number.
Are the elements of the periodic table arranged by their properties?
Elements are arranged by their atomic number. The properties are periodic when arranged in this manner.
What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
A table of elements that organizes the elements by atomic number and properties?
Chemists call this the periodic table of elements.
Has similar properties with elements T but has lower atomic number?
flourine
What are the properties based on modern periodic table?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
