What three charges can an object have?
positive, negative, and neutral
How did Benjamin Franklin discover positive and negative charges?
Benjamin Franklin is famous for his experiments with electricity. Unfortunately, records don't contain a particular experiment where he discovered positive and negative charges.
Who created the first theory that accounted for positive and negative charges?
Probable Thales from Miletus 2 600 years ago.
How was electromagnetism discovered?
Electromagnetism was discovered, per se, by James Clark Maxwell. He was the first to say that positive and negative charges were regulated by one force.
When Benjamin Franklin rubbed a glass rod with a piece of silk?
The silk picked up positive charges.
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.
What are the physical differences between polar and nonpolar molecules?
Polar molecules have an uneven distribution of electrons, leading to regions of partial positive and negative charges. Nonpolar molecules have an even distribution of electrons and no distinct positive or negative regions. This difference in electron distribution affects properties such as solubility, melting point, and boiling point between polar and nonpolar molecules.
How do polar molecules differ from non-polar molecules?
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.
Do Polar molecules such as water have no negative or positive poles?
Polar molecules like water do have distinct positive and negative poles due to an uneven distribution of charge within the molecule. In the case of water, the oxygen atom has a partial negative charge, while each hydrogen atom has a partial positive charge, resulting in a polar molecule.
Characteristics for polar and nonpolar molecues?
Polar molecules have separation of charges .ie. they have a partial positive and partial negative charges on molecule as in water . Non polar molecules e.g.methane has no separation of positive and negative charges as difference of electronegativity in C and H is very small .
What are the two like charges?
a positive and a positive or a negative and a negative. Object with the same charge. Like charges repel each other.
Does water have more positive or negative charges?
That depends on what you consider a charge. Electrons/protons? Compute approx. number of molecules, multiply by 10 for positive or negative charges. Water dipols? Compute approx. number of molecules for positive or negative charges. Ions/Anions? (Technically, this is not part of water, but salt solutions within it) Don't know how many milligrams of salt there is in an average cup of water.
Do ions posses charges?
Yes, ions are charged molecules by definition. There are two types cations (with positive charges) and anions (with negative charges).
What are the 2 types of electric charges?
The two types of electric charges are positive and negative. Positive charges repel each other, as do negative charges, while positive and negative charges attract each other.
Do all objects have a charge?
Not all objects have a charge. Objects can be neutral, meaning they have an equal amount of positive and negative charges that cancel each other out. Only objects that have an unequal distribution of positive and negative charges will have a net charge.
What molecules have a dipole moment?
Molecules with a dipole moment have an uneven distribution of electron density, leading to a separation of positive and negative charges. Examples include water (H2O), ammonia (NH3), and hydrogen chloride (HCl). Symmetrical molecules like carbon dioxide (CO2) typically do not have a dipole moment due to their balanced distribution of charge.
Describes a molecule with opposite charges on opposite ends?
A molecule with opposite charges on opposite ends is called a polar molecule. This occurs when there is an unequal distribution of electrons, leading to regions of positive and negative charge. Water (H2O) is a common example of a polar molecule with oxygen carrying a partial negative charge and hydrogen carrying a partial positive charge.
