What else can I help you with?
An unknown substance is made only of identical atoms that cannot be broken down. This substance is a .?
Element
A substance in which all of the building block particles are identical is called?
An element. The particules are atoms.
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
An unknown substance is made only of identical atoms that cannot be broken down this substance is what?
An Element ... A substance that cannot be broken down into simpler substances by chemical means.
Is hydrogen gas a pure substance?
Yes, hydrogen gas is a pure substance because it consists of only hydrogen atoms. It is a homogeneous mixture of identical molecules, making it a pure substance.
What is matter composed of identical atoms?
Matter is composed of identical atoms that make up elements. These atoms can combine to form molecules through chemical bonds, which in turn create the different substances we observe in the universe. The properties of matter are determined by the type of atoms present and how they are arranged.
How can you use Dalton's atomic theory to explain why every sample of pure substance has the same properties?
Dalton's atomic theory states that elements consist of indivisible particles called atoms and that atoms of the same element are identical in size, mass, and properties. Therefore, every sample of a pure substance will have the same properties because each sample is made up of the same type of atoms arranged in the same way.
What is the substance made up of atoms?
All substances are made up of atoms. Atoms are the basic building blocks of matter and are composed of protons, neutrons, and electrons. These atoms combine to form molecules, which make up different substances.
How are atoms identical?
they are not identical. Dalton's model was wrong.
Are beryllium atoms identical?
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
Is it true that all the atoms of one pure substance are the same but are different from the atoms of another pure substance?
Yes, it is true that all the atoms of a pure substance are identical in terms of the number of protons, electrons, and neutrons, which defines the element. However, atoms of different pure substances are distinct from each other in their atomic structure and properties, such as the number of protons, which determines the type of element. For example, all oxygen atoms are the same, but they differ from all carbon atoms. This fundamental difference is what gives each element its unique characteristics.
Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that?
Because the existence of isotopes was discovered not all atoms of an element are identical.
