Question

Electrons are most likely found near the nucleus, regardless of the type of orbital they 'occupy'. __________ A laser produces monochromatic light. __________ X-rays are made up of extremely high energy photons.__________ A photon of light is equal to one quantum of energy. __________ Ionic compounds have higher melting points than molecular compounds because of strong attractive between particles.____________ The surface tension of water is due to the hydrogen bonding between water molecules.___________ Energy transformations are the basis for all the activities that make up our lives. __________ Chemical systems contain both kinetic and potential forms of energy.___________ The energy of protons and neutrons in the atomic nuclei is a form of potential energy in a chemical ___________ Inside a calorimeter, the amount of energy gained by the surroundings (the water) must equal the energy released by the reaction in the calorimeter. __________ The enthalpy change per mole of a substance undergoing a change is called the molar enthalpy. ____________ Uranium is a very concentrated energy source. ___________ Nuclear fusion occurs naturally in the sun._____________

Explanation / Answer

Ans 1. True

All the atomic orbitals in an atom holding the electrons regardless of their shape are centered towards the nucleus. So the electrons are also most likely to be found near the nucleus.

2 . True

Laser produces monochromatic light , in which all the waves have same wavelength and frequency.

3 . True

X rays are the electromagnetic radiation which are produced when the high speed electrons strike the metal surface.

4. True

Quantum is the samllest unit of anything . And photon is the smallest unit of elctromagnetic radiation. So they are equal.
