Yes they can.
The atoms are different sizes.
A molecule is a group of atoms that are chemically bound together. There are many different atoms such as "H" for Hydrogen or "He" for Helium or "Na" for Sodium. Scientists represent these atoms in different sizes and colours.
Two elements that have atoms of very different sizes means that the cast iron is likely a substitutional alloy.
Intermetallic alloys have metal atoms of different sizes. These alloys are composed of two or more different types of metal atoms that form a specific ordered structure, resulting in unique properties compared to traditional alloys.
Ancient Greek philosophers.
No, Dalton did not say that all atoms are the same size. Instead, Dalton proposed that all elements are composed of indivisible particles called atoms, and that atoms of different elements have different sizes and properties.
No, Dalton's atomic theory did not include the idea that all atoms of all elements are the same size. Instead, he proposed that atoms of different elements have different sizes and weights.
why are raindrops different sizes?
John Dalton imagined atoms to be indivisible and solid spheres that were akin to billiard balls. He believed that atoms of different elements had different sizes and weights, and that they combined in simple whole number ratios to form compounds.
This theory was proposed by the ancient Greek philosopher Democritus. He postulated that all matter is composed of indivisible particles called "atoms" that vary in size and shape to create different substances.
Leucippus and Democritus characterized the smallest unit of matter as indivisible particles called atoms, which they believed were in constant motion in empty space. They proposed that different types of atoms had different sizes, shapes, and properties, and that the interactions between these atoms determined the properties of substances.
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
