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?
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.
Why an atom must contain positive charges as well as negative charges.the letter should also explain why Thomson proposed the atomic model that he did?
An atom must contain both positive and negative charges to ensure electrical neutrality; the negative charges from electrons balance the positive charges from protons. J.J. Thomson proposed the "plum pudding" model of the atom in 1897, suggesting that atoms were composed of a positively charged “soup” with negatively charged electrons embedded within it. This model arose from his experiments with cathode rays, which demonstrated the existence of electrons, leading him to envision a structure where these electrons were suspended in a positively charged matrix.
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.
Who descibed the atoms as negative charges scattered through a ball of positive?
J . J Thomson
What are the properties of an atom that determine its interaction with other atoms based on the presence of positive and negative charges?
The properties of an atom that determine its interaction with other atoms based on the presence of positive and negative charges are its atomic number, electron configuration, and the distribution of positive and negative charges within the atom. These factors influence how atoms bond with each other to form molecules.

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.
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.
