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".

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.
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.
What is the Thomson model of the atom?
J.J. Thompson's model of the atom is also known as the "plum pudding" model. Thompson modeled the atom as a mixture of positive protons amongst negatively charged electrons.Ernest Rutherford proved this model to be incorrect when he showed that the positive protons of an atom are located in the central nucleus. If the nucleus of a hydrogen atom were expanded to the size of a tennis ball, the electrons surrounding the nucleus would be (on average) several kilometers away from the nucleus.
What is Niels Bohr's model of the hydrogen atom?
The Bohr model for hydrogen is a proton orbited by an electron.
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 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.
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.
The model of the atom includes a positively charged center or?
The model of the atom includes a positively charged center or nucleus. The nucleus consists of protons and neutrons, collectively nucleons.
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.
What is the Thomson model of the atom?
J.J. Thompson's model of the atom is also known as the "plum pudding" model. Thompson modeled the atom as a mixture of positive protons amongst negatively charged electrons.Ernest Rutherford proved this model to be incorrect when he showed that the positive protons of an atom are located in the central nucleus. If the nucleus of a hydrogen atom were expanded to the size of a tennis ball, the electrons surrounding the nucleus would be (on average) several kilometers away from the nucleus.
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.
Which model of the atom states that electrons are located in set around nucleus?
Bohr's model
Which model of the atom states that electrons are located in orbits around the nucleus?
Bohr's model
What is Rutherfords model of the atom?
the nuclear model was its name. the theory behind this model is that 99.99% of the atom is empty space.the nucleus is what that is tiny and the most dense positive core.The nucleus contains protons. the nucleus is what weight the most in the atom
What are the three main particles in the model of an atom?
Proton, Neutron, and Nucleus.
