Since all atoms have negatively charged electrons, shouldn’t every sample of matter have a negative charge ? Explain
Salsk061 [2.6K]

The three sub-atomic particles that made up an atom are electron, proton and neutron. The proton and neutron are present in the nucleus of an atom whereas electrons revolve around the nucleus in the orbits. The atoms are electrically neutral that is they have no charge due to the presence of equal number of protons (which is positively charged) and electrons (which is negatively charged).

All the atoms have negatively charged electrons which are counter balanced by the presence of equal number of protons in the nucleus of an atom and thus, the element is neutral in nature and possess no charge.

Which element rarely reacts because it has 8 electrons in its outer shell?
mojhsa [17]

Answer:

C. Arsenic

Explanation:

Each period is terminated by a noble gas with a closed valence shell with electronic configuration ns²np⁶. Since noble gases have completely filled orbitals in the valence shell and are very stable, it becomes very difficult to alter their stable arrangement by the addition or removal of electrons. They they exhibit very low chemical reactivity.

Noble gas elements are: Neon, Argon, Krypton, Xenon, Radon, Helium (2 electrons in outer shell, stable).

As electricity flows through a copper wire, the temperature of the wire increases. Some parts of the wire get warmer than others
mezya [45]

Answer:

Conduction

Explanation:

The heat can be transferred in the substances in three ways: conduction, convection, and radiation.

The conduction happens inside the material, usually a solid, and the heat flows as the molecules of the substance are agitated. The convection happens when there are different substances in touch, so it is the heat passage from a solid to a liquid or gas, from a gas to a liquid or vice versa. The radiation occurs between substances that are far away and the heat flows by electromagnetic waves.

Thus, in the wire, the heat flows by conduction.
