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.

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?
A neutral atom has not an electrical charge; only cations have a positive charge. Using an electrochemical cell with two electrodes (anode and catode) you can determine the charge of ions in the solution.
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.
Why are a neutral atoms positive and negative charges balanced?
For the atom to be neutral, the positive and negative charges must cancel each other out.
Atoms have a positive change when?
Protons contribute positive charges to atoms, while electrons contribute negative charges. An atom will have an overall positive charge if it has more protons than it does electrons. This most commonly occurs when an atom loses an electron or two, like what is common with alkaline and earth metals.
Who descibed the atoms as negative charges scattered through a ball of positive?
J . J Thomson
How did Thomson know that atoms must contain particles with positive charges?
He knew that in a vacuum tube metals can be made to emit streams of negative charge which were then called cathode rays. If atoms are neutral and can produce negative charge, there must be positive charge there too.
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.
Who discovered that atoms have negative electric charge?
There were several scientists that discovered that atoms contained electric charges. One of the first to look at their charges more closely was J.J. Thomson.
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.
Why did scientists know that atoms have positive charges?
A neutral atom has not an electrical charge; only cations have a positive charge. Using an electrochemical cell with two electrodes (anode and catode) you can determine the charge of ions in the solution.
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.
What is a group of atoms with with a positive or negative charge?
A polyatomic ion is a group of atoms with a 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.
