What is divisible by chemical or nuclear means atoms or molecules?
Atoms: smallest unit of an element. Molecule: smallest unit of a compound., combination of atoms of the same or different elements., a group of atoms chemically bonded together. Both: divisible by chemical or nuclear means, smallest unit that can be isolated through physical changes.
Who discovered that atoms is divisible?
The discovery that atoms are divisible is attributed to various scientists over time, but a key figure in this realization was J.J. Thomson. In 1897, he discovered the electron, demonstrating that atoms are not indivisible but composed of smaller subatomic particles. This finding marked a significant shift in atomic theory, leading to further exploration of atomic structure by later scientists, including Ernest Rutherford and Niels Bohr.
Did democritus believe matter was infinitely divisible?
Democritus did not believe that matter was infinitely divisible. Instead, he proposed that matter is composed of small, indivisible particles called atoms, which cannot be divided further. He theorized that these atoms are the fundamental building blocks of all matter, and while they can combine in various ways to form different substances, the atoms themselves remain indivisible. This idea marked a significant departure from the notion of continuous matter.
Is 402 a prime number?
402 is divisible by 2.402 is divisible by 2.402 is divisible by 2.402 is divisible by 2.
Is 1114 a prime or composite number?
1114 is divisible by 2.1114 is divisible by 2.1114 is divisible by 2.1114 is divisible by 2.
Smallest units of matter nondivisible by chemical means?
Atoms are the smallest units of matter that cannot be divided by chemical means. Each atom is made up of a nucleus containing protons and neutrons, surrounded by electrons.
What is the smallest unit of matter that can enter chemical reactions and is nondivisible by chemical means?
An atom.
Did Aristotle think atoms are indivisible?
No, Aristotle did not believe in the existence of atoms. He believed that all matter was continuous and infinitely divisible.
What is divisible by chemical or nuclear means atoms or molecules?
Atoms: smallest unit of an element. Molecule: smallest unit of a compound., combination of atoms of the same or different elements., a group of atoms chemically bonded together. Both: divisible by chemical or nuclear means, smallest unit that can be isolated through physical changes.
What did radioactivity reveal about the structure of atoms?
It showed that atoms were divisible, there were subatomic particles within the atom. Atoms could change form and emit an enormous amount of energy.
Is an atom indivisible elaborate your answer?
No. Atoms are now considered to consist of several minor particles. And atoms dividing is what provides the energy for nuclear power plants. So atoms are NOT indivisible. They ARE divisible.
Can molecules break apart into atoms during a chemical change?
No, being that atoms are only divisible under special spectrometry conditions in a laboratory.
Are all composite numbers divisible by 2?
No. For example, 21 has factors 1, 3, 7 and 21 making it composite, but is odd (nondivisible by 2).
What observations led scientists to propose the existence of subatomic particles?
Atoms were found to be divisible after all . But scientists discovered that the atoms were made of smller perticles , called subatomic particles.
Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that .?
It is now known that atoms can be divided into subatomic particles (protons, neutrons, electrons) and that isotopes of an element can have different numbers of neutrons. Atoms are not indivisible and they can differ in properties even within the same element.
What is the building blocks of a compound?
The building blocks of a compound are atoms. Atoms combine together to form molecules, which in turn make up compounds. The specific types of atoms and how they are bonded together determine the properties and characteristics of the compound.
Who said matter is not infinitely divisible?
The Greek philosopher Democritus (460-370 B.C) believed atoms could not be created, destroyed, or further divided.
