Is radioactivity a spontaneous process? Radioactive decay is by definition a spontaneous process in which the nuclei of unstable isotopes emit radiation as they are converted to more stable nuclei. All the decay processes occur spontaneously, but the rates at which different isotopes decay vary widely. Does spontaneous mean random? As adjectives the difference between […]

Why is Aluminium ductile in terms of structure?
Why is Aluminium ductile in terms of structure? The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into […]

What are causes of ocean acidification?
What are causes of ocean acidification? Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water’s pH, making the ocean more acidic. Many factors contribute to rising carbon dioxide levels. What happens during ocean acidification? When carbon dioxide (CO2) is absorbed […]
What do the rows mean on a periodic table?
What do the rows mean on a periodic table? Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels. How do you identify […]
