Explanation:
The cations and anions are locked tightly into place because of the attraction of their opposite charges - as a result, it's difficult to move the ions and the material is very hard.
Answer is: no, every sample does not have a negative charge.
Beside negatively charged electrons, atoms have positively charged protons, so atoms have neutral charge.
Atomic number is the number of protons, which is characteristic of a chemical element. For example, iron (Fe) is an element with atomic number 26, which means it has 26 protons and 26 electrons (in neutral atom, number of protons is equal to number of electrons).
The electron (symbol: e⁻) is a subatomic particle whose electric charge is negative one elementary charge.
Proton is a subatomic particle with a positive electric charge of +1e elementary charge.
Answer:
thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat
