Why the energy that we feel from the sun is mostly radiation?         It depends on the distance between the Sun and the Earth       Due to lower thermal conductivity value of the air       Due to the nuclear reactions inside the sun       Not sufficient information

Copper is a typical face-centered-cubic metal. In its pure state, it has extremely high electrical conductivity. Oxygen in copper causes a major reduction of conductivity. To investigate this issue further, I want to you to tell me whether oxygen atoms substitute for copper atoms, or if they enter interstitial sites.

According to the Bohr model of the atom   a. electrons in orbit around nuclei lose energy very slowly   b. electrons around a nucleus can have only certain particular energies and can only occupy certain specific orbits at particular distances from the nucleus   c. quantum theory is not applicable to the ultra-structure of an atom   d. all of the options are true

Q: Not considering the many subatomic particles, name the three basic components of which atoms are made. What differences are there among the three? A:  The three (3) basic components of which atoms are made, The ___________, which has a positive (+) electrical charge, and the _____________ , which has a neutral electrical charge, make up the nucleus. ___________ are particles of negative (-) electric charge which surround the nucleus in shells or orbitals.
