To determine the period to which carbon belongs, we can follow these steps:Step 1: Identify the Atomic Number of Carbon Carbon has the atomic number 6. This means it has 6 protons and, in a neutral atom, also 6 electrons.
(c) Carbon dioxide, CO2, is a covalent molecule.Complete the diagram to show the electron arrangement in one molecule of CO2.Show only the outer electrons.0C O2(d)The graph shows the concentration of carbon dioxide in the atmosphere over a 60-year period,measured in parts per million (...

They say the effects of fast climate change in the Cretaceous period are similar to what scientists are seeing now from climate change.Peterson says the volcano eruption before the meteorite increased pressure on Earth\'s environment. In that same way, the carbon dioxide gas emissions from human...
Cisplatin-induced oxidative stress triggers rapid shifts in carbon flux in 3 commonly utilized catabolic pathways: glycolysis, pentose phosphate pathway and citric acid cycle. Among these metabolic shifts, decreased flux from pyruvate into lactate is the only metabolic effect consistently observed across ...
