Who is the scientist that grouped elements into sets of three?
Newland, Moseley, , Dobereiner, Mendeleeff...
Which elements have similar chemical properties in sulphur and helium?
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
What is an organizational tool used by scientist to order the elements by atomic number and similar properties?
The organizational tool used by scientists to order the elements by atomic number and similar properties is called the periodic table. It is a grid that arranges elements in rows and columns based on their atomic structure, allowing for easy comparison of elements with similar characteristics.
What is a tool scientist use to organize the elements?
The elements are arranged in the increasing order of their atomic number and repeating properties.
Who was the scientist who observed a pattern of properties that repeated every eight elements?
The scientist who observed the pattern of properties that repeated every eight elements was John Newlands. He created the Law of Octaves, which grouped elements based on similar properties and noted the repetition every eighth element.
Why might it be important for scientist to know hell elements are similar or different?
It is important for scientists to know how elements are similar or different because it helps them understand the properties of different elements, how they interact with each other, and their behavior in various chemical reactions. This knowledge is essential for developing new materials, predicting how substances will behave in different conditions, and advancing scientific research and technology.

Are copper and silver similar or different?
Copper and silver are both metallic elements, but they have different properties. Copper is reddish-brown in color, while silver is shiny and white. They also have different melting points and densities.
Which elements have similar chemical properties in sulphur and helium?
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Which scientist proposed the law of octaves?
The scientist who proposed the law of octaves was John Newlands in 1864. He noticed that when the elements were ordered by atomic weight, every eighth element had similar properties, similar to the musical concept of octaves.

What is the chemical behavior of different elements and what is it determined by?
The chemical behavior of different elements is determined by their electron configurations. Elements with similar electron configurations exhibit similar chemical behavior. For example, elements in the same group of the periodic table tend to have similar chemical properties due to their shared electron configurations.
Who arranged the elements into triads?
Dmitri Mendeleev arranged the elements into triads in the periodic table. Mendeleev noticed that elements with similar properties occurred at regular intervals when arranged by increasing atomic mass.
How can a scientist using the periodic table find and element with properties similar to another element?
A scientist can find an element with properties similar to another by looking at elements in the same group or column of the periodic table. Elements in the same group tend to have similar chemical properties due to their similar outer electron configurations. This allows scientists to predict the behavior of an element based on its position on the periodic table.
How did the Russians scientist first arrange the elements?
Russian scientist Dmitri Mendeleev first arranged the elements in the periodic table based on increasing atomic mass and similar properties. He left gaps for undiscovered elements and predicted their properties, which led to the discovery of new elements. Mendeleev's periodic table laid the foundation for the modern periodic table we use today.
