What else can I help you with?
Who said that each element is composed of extremely small particles called atoms?
Someone Rutherford.
Who is The schoolteacher who studied atoms and proposed an atomic theory?
The schoolteacher who studied atoms and proposed an atomic theory was John Dalton, known for his development of modern atomic theory in the early 19th century. Dalton's theory proposed that all matter is composed of small, indivisible particles called atoms that are unique to each element and are rearranged in chemical reactions. His work formed the foundation for modern chemistry.
What is everything made of and is the smallest of units of an element?
Everything is made of atoms, which are the smallest units of an element. Atoms are composed of even smaller particles called protons, neutrons, and electrons.
Is an element composed of millions of identical atoms?
Yes, an element is composed of millions of identical atoms.
What is the most toxic substances on earth of element is?
The most toxic element on Earth is considered to be polonium, specifically polonium-210. It is a highly radioactive element that emits alpha particles, making it extremely toxic if ingested or inhaled. It is about 250,000 times more toxic than hydrogen cyanide.
Who said that each element is composed of extremely small particles called atoms?
Someone Rutherford.
What is sodium and what is made out of it?
Sodium is a metallic element and is composed of sub-atomic particles.
The tiny particles that comprise an element are?
Atoms. Which are composed of protons, neutrons and electrons.
Who proposed the atom theory that all matter is composed of atoms and that all atoms of an element are alike?
John Dalton proposed the atom theory in the early 19th century. He suggested that all matter is made up of tiny, indivisible particles called atoms, and that all atoms of a specific element are identical in size, mass, and properties.
What is the simplest organized substance know although it is to composed of small particles?
The simplest organized substance known is an element, which is composed of small particles called atoms. Each type of element has a unique structure and properties based on the arrangement of its atoms.
Who is The schoolteacher who studied atoms and proposed an atomic theory?
The schoolteacher who studied atoms and proposed an atomic theory was John Dalton, known for his development of modern atomic theory in the early 19th century. Dalton's theory proposed that all matter is composed of small, indivisible particles called atoms that are unique to each element and are rearranged in chemical reactions. His work formed the foundation for modern chemistry.
Are elements particles?
yes
Is gas made of tiny particles?
Yes, everything is made of tiny particles - if it is an element then the particles are atoms of that element, if it is a compound then the particles are molecules composed of atoms of the elements which make up the compound.
What element is diamond composed of?
Diamond is composed of the element carbon.
Are elements the smallest type of substance?
Elements are the simplest type of chemical. An element is composed of atoms. Atoms in turn are composed of subatomic particles. However, all substances are composed of atoms, and there are no substances composed only of subatomic particles - at least, not on Earth. It is believed that there exist neutron stars composed only of neutrons. In that situation, you could say that the neutron is the smallest type of substance.
What was Aristotles theory on particles?
Aristotle believed in a fifth element called "aether" or quintessence, which he believed composed celestial bodies. He proposed that matter was made up of four elements: earth, water, air, and fire. These elements combined in different proportions to form all substances in the physical world.
What is everything made of and is the smallest of units of an element?
Everything is made of atoms, which are the smallest units of an element. Atoms are composed of even smaller particles called protons, neutrons, and electrons.
