What element is similar to nickel? Metal Can nickel exist as a gas? Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Nickel is classified as a “Transition Metal” which are located in Groups 3 – 12 of the Periodic Table. What […]

Can an elliptical galaxy evolve into a spiral can a spiral turn into an elliptical How?
Can an elliptical galaxy evolve into a spiral can a spiral turn into an elliptical How? We know this because spiral galaxies rotate quickly (on an astronomical scale), while elliptical galaxies do not. There is no way that an elliptical galaxy could spontaneously begin rotating, so there is no way an elliptical galaxy could turn […]

Do longitudinal waves have nodes?
Do longitudinal waves have nodes? Longitudinal wave – a wave that is propagated in the same direction as the displacement of the transmitting medium. Node – A node is a point along a standing wave where the wave has zero amplitude. A wave center is stable at the node of the standing wave. What is […]
What are the causes of shortage of electricity?
What are the causes of shortage of electricity? There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Why electricity is harmful? […]

Is nitrous acid present in acid rain?
Is nitrous acid present in acid rain? Industrial areas tend to release nitrous oxides gas, or chlorine gas or sulfurous gas into the atmosphere, when these gases combine with water from the acid rain, they are turned to nitric acid (HNO3), chloric acid (HCl) or sulfuric acid (H2SO4) respectively. Is sulphurous acid present in acid […]
What is the best way to separate the mixture?
What is the best way to separate the mixture? Summary Mixtures can be separated using a variety of techniques. Chromatography involves solvent separation on a solid medium. Distillation takes advantage of differences in boiling points. Evaporation removes a liquid from a solution to leave a solid material. Filtration separates solids of different sizes. Who will […]
Why do electrons want a full outer shell?
Why do electrons want a full outer shell? The valence electrons (outer-most electrons) determine most of the bonding behavior in atoms. Atoms want a full outer shell because it completes all the gaps in the outside. With no gaps, other electrons don’t want to fit into those spaces. For example, a noble gas like Neon […]
