Nelson Mandela did not arrange chemical elements; this task is attributed to Dmitri Mendeleev, who created the Periodic Table of elements in the 19th century. Mendeleev organized elements based on their atomic mass and similar chemical properties, allowing for predictions about undiscovered elements. Mandela, on the other hand, was a prominent anti-apartheid activist and the first black president of South Africa, known for his leadership in social justice and human rights rather than scientific contributions.
What else can I help you with?
Howdid moseley arrange chemical elements?
He arranged the elements in order of atomic number.
According to the increasing of what did Medeleev arrange the known chemical elements in a table?
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
Mendeleev arrange the known chemical elements in a table according toincreasing?
Mendeleev arranged the known chemical elements in a table according to increasing atomic mass and similar chemical properties. This arrangement led to the periodic table of elements, where elements with similar properties fall into the same column or group. This organization allowed Mendeleev to predict the properties of undiscovered elements and leave spaces for them in the table.
What arrange the known elements into groups and periods?
The periodic table
How many elements did Antoine Lavoisier arrange?
he grouped the table into metals, non metals and gases.
Howdid moseley arrange chemical elements?

According to the increasing of what did Medeleev arrange the known chemical elements in a table?
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
What three groups do scientist arrange elements into?
Scientists arrange elements into metals, nonmetals, and metalloids based on their physical and chemical properties. Metals are typically good conductors of electricity, nonmetals are poor conductors, and metalloids have properties of both metals and nonmetals.
How do you use the periotic table?
You get a copy and pin it to your wall. All the elements are arrange on it in a sensible way, summarizing their physical and chemical attributes. As you get familiar with it you will be able to use it to predict the chemical and physical properties of new elements you are to be taught about.
How did this Russian scientist first arrange the elements?
Dmitri Mendeleev arranged the elements in his periodic table based on their atomic masses and chemical properties. He left gaps for undiscovered elements and predicted their properties accurately.

Mendeleev arrange the known chemical elements in a table according toincreasing?
Mendeleev arranged the known chemical elements in a table according to increasing atomic mass and similar chemical properties. This arrangement led to the periodic table of elements, where elements with similar properties fall into the same column or group. This organization allowed Mendeleev to predict the properties of undiscovered elements and leave spaces for them in the table.
What is the arrange of elements call?
The elements are arranged in what is called the periodic table.
How do you build a compound from the chemical formula?
To build a compound from a chemical formula, first identify the elements present in the formula. Then, determine the ratio of each element in the compound. After that, use this information to arrange the atoms in the correct structure following the rules of chemical bonding.
When elements are arrange in order of increasing atomic no is called?
The Periodic Table of Elements.
Who was the first scientist to arrange the chemical elements in order of their atomic weights?
Dmitri Mendeleev is credited with arranging the chemical elements in order of their atomic weights. His work led to the development of the periodic table of elements.
