6 0

At first sight it doesn't bode well. The key is in how firmly the protons and neutrons are held together. In the event that an atomic response produces cores that are more firmly bound than the firsts then vitality will be created, if not you should place vitality into make the response happen.

Which of the pairs of elements listed will form an ionic bond? a Potassium-Chlorine b Hydrogen-Carbon c Oxygen-Oxygen d Nitrogen

Mashutka [201]

An ionic bond forms between an elemental metal and non-metal, characterized by the transfer of electrons from the metal to the non-metal in an attempt to mimic the stable octet.

A is the correct answer, as Potassium (a group 1 alkali metal) will donate an electron to Chlorine (a group 17 halogen). Potassium becomes more stable by removing the outermost shell, leaving behind a stable octet, and Chlorine completes its shell with the addition of the new electron. This trade of electrons forms their “ionic” forms, hence the reason for calling it an ionic bond. The other three form covalent bonds.

The greater the friction, or rubbing, between particles in any fluid, the higher the viscosity. A fluid with a high viscosity has a large amount of internal friction. As the temperature of a gas increases, friction increases, and so the viscosity of the gas increases. The warmer the gas, the slower it flows.
