Why do atoms get bigger across a period? 4 Answers. As you move from left to right across a period, the number of protons in the nucleus increases. These lower energy levels shield the valence electrons from the attractive effects of the atom’s nucleus, so the atomic radius gets larger. Why do atoms get smaller […]

Why is south facing garden better than north? The main advantage of a south-facing house or garden is the amount of sunlight you’ll enjoy. As the sun rises in the east and sets in the west, the south side of any house will see the most hours of sunlight during the day – especially in […]

How fast can a freight train accelerate? The final factor and one frequently overlooked is the tractive effort required for acceleration of the train. It takes about 10 pounds per ton to accelerate to a speed of 6 miles per hour in one minute or 12 miles per hour in two minutes, a reasonable rate […]

Do air bubbles get bigger? The bubble gets bigger when it go up to the surface because there is less pressure as it rises to the surface. Air is less dense than water and thus the force of gravity is less on the bubble than on the surrounding water then the bubbles rise. What happens […]

What can be the cause of weakening muscles and kidney function? When muscle is damaged, a protein called myoglobin is released into the bloodstream. It is then filtered out of the body by the kidneys. Myoglobin breaks down into substances that can damage kidney cells. Rhabdomyolysis may be caused by injury or any other condition […]

Is F2 a single or double bond? On the right is the F2 molecule. The diatomic fluorine molecule (F2) contains a single shared pair of electrons. Each F atom also has three pair of electrons that are not shared with the other atom. Is h2 a single or double bond? Hydrogen forms 1 single bond […]

How many neutrons does 19 9 F? 10 neutrons Is fluorine-19 an ion? According to the periodic tale, fluorine, F, has an atomic number of 19. We can conclude that fluorine gained an electron to reach a stable octet configuration, and because it has an extra electron it is now called a fluorine ion. Why […]

Why is de Broglie relationship is only for microscopic objects? The wave nature of matter, however, has no significance for objects of ordinary size because wavelength of the wave associated with them is too small to be detected. Thus, de-Broglie concept is significant only for sub-microscopic objects in the range of atoms, molecules or smaller […]
