The electroscope is an instrument for detecting an electric charge by measuring mechanical forces between two charged bodies.
The sphere of an electroscope is always neutral at first. Let's say a negative ebonite rod is brought close but not touching the sphere. (The entire electroscope is neutral). The electrons in the electroscope will want to repell the electrons in the rod so the electrons in the electroscope move down into the 2 leaves and then repell because there is a high concentration of negatives. When the ebonite rod is removed, the leaves go back to their straight position. The electroscope is always neutral but only a charge distibution occured. The number of protons and electrons remain the same. However if a charged rod touches the sphere then the electroscope will be charged because it a conductor and the charge from the rod transfers to the electroscope because the rod's caharges want to attarct to the electroscope's opposite charges. This is called charging by contact.
The difference between gas and plasma is the physical structure. The gas turns into a plasma when the gas becomes ionized and loses its positively charged particles. They are similar because they both have no definite shape, but plasma responds strongly to magnetic fields and also emits 5x the electricity it puts in.
electric force
The principle is that there is a force of repulsion between two objects that are both charged with the same sign of charge, i.e. both negative or both positive.

An onion is a delicious vegetable whereas a cation is a positively charged ion.
Whether a plant responds positively or negatively to a stimulus (sun/light, water, nutrients, etc.)
A proton is positively charged; a neutron has no charge and an electron is negatively charged, that is why it is attracted to the atom, which consists of protons.

Molecular Ions essentially consist of the same type of atoms (most probably the atoms of the same element) and the radicals may not have the same characteristic.
Metal ions are typically positively charged, while nonmetals are typically negatively charged.
Classical Aggregate Supply function is vertical whereas the Keynesian Aggregate Supply function is positively sloped.
A gas is composed of atoms (noble gases) and molecules, such as oxygen gas. Plasma is composed of positively charged ions and unbound electrons.
An element has it's protons balanced with electrons. The ion of an element is unbalanced: either positively charged if it lost an electron or negatively charged if it gained one.
it's a simultanious attraction between a positively charged ion and a negatively charged ion it's a simultanious attraction between a positively charged ion and a negatively charged ion
Neutron is a neutral particle present within the nucleus of an atom. Proton is a positively charged particle present within the nucleus of an atom. Photons are particles of light.
