What scientist discovered that atoms have energy level?
The scientist who discovered that atoms have an energy level is Niels Bohr in 1913. According to his model electrons move around the nucleus much the same as the planets rotate around the sun.
What scientist concluded the nucleus of an atom contains a dense center of positive charge?
Ernest Rutherford concluded that an atom contains a very small, dense center, called a nucleus, with a positive charge as a result of his gold foil experiment.
How is static electricity made?
=Usually, atoms have the same number of electrons and protons. Then the atom has no charge, it is "neutral." But if you rub things together, electrons can move from one atom to another. Some atoms get extra electrons. They have a negative charge. Other atoms lose electrons. They have a positive charge. When charges are separated like this, it is called static electricity.=
What were JJ Thomson's discovery?
J.J. Thompson worked to develop the atomic theory. He discovered that atoms have separate negative and positive material. Before him, it was widely believed that atoms were just spheres of matter.
Describe the charges and types of particles that make up all atoms?
The three particles that make up an atom are:electron,proton and neutron. ELECTRON has a negative charge PROTON has a positive charge and NEUTRON has a neutral charge i.e, it contains an equal number of positive and negative charge
When electrons were discovered scientist inferred that neutral atoms contain positive charges because?
Scientists inferred that nuetral atoms contained postitive charges, because electrons contained negative charges.
Who discovered the positive charge of a nucleus?
Ernest Rutherford is the scientist that discovered the positively charged nucleus.
What is the name of the scientist who discovered that atoms have positive charged?
Ernest Rutherford is the name of the scientist who discovered that atoms have positively charged nuclei.
Atoms have higher number of positive charges than negative charges?
the positive number of a atom
Atoms have a higher number of positive charges than negative charges?
Cations, positively charged atoms e.g. Na+. The positive charges are the protons min the nucleus and the negative charges are electrons.
Which scientist was the first to conclude through experimentation that atoms have positive charges in their nuclei?
Hans Geiger and Ernest Marsden. Rutherford was the supervisor and explained the unexpected results, so his name is usually attached to the experiment as well, but it was Geiger and Marsden who actually did it.
Do atoms have a higher number of positive charges or negative?
Normally atoms are neutral.
Which british scientist first disvored atoms and nucleus?
british scientist discovered the nucleus
How did Thomson determine that there was also positive charges found in atoms?
He knew there were electrons which have negative charges, but the overall charge of the atom was zero. There had to be positive atoms for this to be true, because negative and positive charges cancel each other out in order for the overall charge to be zero.
Who discovered the different parts of the atom?
well, lots of scientists discovered different parts of atoms. The scientist who discovered atoms was called dimeter, then, there where lots of other parts of atoms, such as Tomson, Bohr...
What are the two electric charges?
There are two types of charges: positive charges and negative charges. Positive charges are immobile, and are found inside the nuclei of atoms as Protons. Negative charges can be mobile, and have the source of electrons. These orbit the nuclei of atoms, and can be stripped from the atoms to be used as mobile charged through conductors, such as electricity moving through wires.
Scientist who discovered that atoms contained electric charge?
Benjamin franklin
