What is nuclear fission explain with example? Fission is the splitting of an atomic nucleus into two or more lighter nuclei accompanied by energy release. The energy released by nuclear fission is considerable. For example, the fission of one kilogram of uranium releases as much energy as burning around four billion kilograms of coal. What […]

What is the total charge of oxygen?
What is the total charge of oxygen? -2 Does atomic mass change in beta decay? The atomic mass number does not change because a beta particle has a much smaller mass than the atom. The atomic number goes up because a neutron has turned into an extra proton. Beta decay is fundamentally different from alpha […]
Which element would most likely form a covalent bond with a chlorine atom?
Which element would most likely form a covalent bond with a chlorine atom? Answer: It forms from two hydrogen atoms, each with one electron in a 1s orbital. Both hydrogen atoms share the two electrons in the covalent bond, and each acquires a helium-like electron configuration. A similar bond forms in Cl2. Which one of […]

Do neutron stars last forever?
Do neutron stars last forever? Neutron stars cannot stay hot forever. Neutron stars cool because they radiate. (This is called radiational cooling.) Except for their gravitational field which distorts spacetime in the vicinity of a neutron star, most lone neutron stars slowly fade away over time, eventually becoming essentially invisible. Are neutron stars immortal? Massive […]
