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.

Thomson discovered positive charges in atoms through his experiments with cathode rays. He observed that when the cathode rays were deflected by a magnetic field in a cathode ray tube, there were particles with positive charge present. This led him to propose the existence of positively charged particles, later identified as protons.

Who first Proposed the idea that atoms had positive and negative parts?
The idea that atoms had positive and negative parts was first proposed by J.J. Thomson in the late 19th century through his "plum pudding" model of the atom. Thomson suggested that atoms were composed of positive and negative charges distributed throughout a neutral sphere, like plums in a pudding.
What did Thomson call electrons?
Thomson believed about atoms, that : An atom consists of a sphere of positive charge with negatively charged electrons embedded in it. Positive and negative charges in an atom are equal in magnitude, thus an atom is electrically neutral and it has no overall + or - charge.
Why did scientists know that atoms have positive charges?
Scientists discovered that atoms have positive charges through experiments like the Cathode Ray Tube experiment, which showed that atoms contain positive and negative particles. This led to the development of the atomic model and the understanding that atoms have a nucleus with positively charged protons.
When electrons were discovered scientist inferred that neutral atoms contain positive charges because?
When electrons were discovered, scientists inferred that neutral atoms contain positive charges because electrons have a negative charge and atoms were found to be neutral overall. This led to the conclusion that atoms must contain positively charged particles to balance out the negative charges of electrons, thus making atoms electrically neutral.
What atoms have no overall charge?
Atoms with no overall charge are called neutral atoms. They have the same number of protons, which carry a positive charge, and electrons, which carry a negative charge. This balance of positive and negative charges leads to a neutral overall charge for the atom.
Who descibed the atoms as negative charges scattered through a ball of positive?
J . J Thomson

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.
Do atoms have a higher number of positive charges or negative?
Normally atoms are neutral.
Why did scientists know that atoms have positive charges?
Scientists discovered that atoms have positive charges through experiments like the Cathode Ray Tube experiment, which showed that atoms contain positive and negative particles. This led to the development of the atomic model and the understanding that atoms have a nucleus with positively charged protons.
Who discovered that atoms have negative electric charge?
J.J. Thomson is credited with discovering that atoms have negative electric charge through his work with cathode rays and the discovery of the electron in 1897.
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.
What is the name of he scientist that discovered that atoms have positive charges?
Ernest Rutherford was the scientist who discovered that atoms have positive charges through his gold foil experiment, which led to the development of the nuclear model of the atom.
Do ionic bonds form between ionized atoms?
Yes, only if there are both ions with positive charges and ions with negative charges among the ionized atoms.
When electrons were discovered scientist inferred that neutral atoms contain positive charges because?
When electrons were discovered, scientists inferred that neutral atoms contain positive charges because electrons have a negative charge and atoms were found to be neutral overall. This led to the conclusion that atoms must contain positively charged particles to balance out the negative charges of electrons, thus making atoms electrically neutral.
Why does it matter if something is negative or positive in electricity?
(in case of an atoms) negative charges or positive charges will over power the other side and the whole atom will be disorted
