Democritus, an ancient Greek philosopher living around400 BC, is credited with creating the original theory of atoms. He coined the word "atomos", which means "indivisible". He stated that all matter is made up of atoms. Democritus's model of an atom consisted of a smooth, hard ball. He said that atoms are indestructible and always in motion. Democritus thought that atoms differ in shape and size. There is an infinite number of atoms and infinite kinds of atoms. Although many of his theories have since been proven false, Democritus is considered "the father of modern science".
What else can I help you with?
Who developed the first model of an atom with electrons on the outside?
Ernest Rutherford developed the first nucleus and electron model of the atom. It was based on experiments conducted by Geiger and Marsden.
A model of the atom with electrons moving around a positively charged nucleus was fist purposed by?
Neils Bohr first proposed a model of the Atom that was like the Solar System with its Planets (Electrons) orbiting around the Sun (Nucleus). The orbits of the Electrons were considered to be Pre-Defined, but they could JUMP between orbit levels with the addition or subtraction of energy to the Atom.
Who was the scientist who first proposed that electrons existed in only certain energy level about nucleus?
The scientist who first proposed that electrons existed in only certain energy levels around the nucleus was Niels Bohr. His model of the atom, known as the Bohr model, introduced the concept of quantized energy levels and provided a framework for understanding the behavior of electrons in atoms.
Who drew the atom as a nucleus surrounded by electrons?
Dalton 'drew' the first atom, however, this was essentially a circle with a letter in it. The popular version of the atom, as seen today, was theorized by Rutherford.
What is Bohrs model an atom?
Bohr's model of the atom, proposed by Niels Bohr in 1913, described the atom as having electrons orbiting the nucleus in specific energy levels or shells. It introduced the concept of quantized energy levels and laid the foundation for understanding atomic structure.

Describe the planetary model of an atom?
The planetary model of an atom is simple. The nucleus is the planet and the electrons are the moons in the model.

Were is the nucleolus on a Bohr model?
An atom does not have a nucleolus, but it does have an atomic nucleus which is located in the center of the atom, including the Bohr model.
How do you make a 3D model of vanadium?
you will need to know how many protons, neutrons and electrons your vanadium atom has. The nucleus, the central part of the atom, all of your atom's protons and neutrons go in the nucleus, The electrons are found outside the nucleus. Depending on which model of atomic structure (Planetary Model, Bohr Model) your are studying your electrons will be placed.
How can the model of the nuclear atom be describe?
a nucleus in an electron cloud.
When did Niels Bohr made a model of the atom?
Niels Bohr proposed his model of the atom in 1913, which is known as the Bohr model. This model introduced the idea of quantized energy levels for electrons in an atom, revolutionizing our understanding of atomic structure.
Which model of the atom states that electrons are located in set around nucleus?
Bohr's model
How did Niels Bohr create his atom model?
Niels Bohr placed in the center of atom the atomic nucleus and electrons in movement around nucleus.
