Which element is most likely to bend without breaking? carbon (c) iodine (i) silicon (si) cobalt (co)

The answer is Cobalt (Co). Iodine is a gas at room temperature so it is out of the question. Carbon is non-metal so its common allotrope which is graphite is very brittle. Brittleness is a mechanical property of a material to break easily upon the application of a force, which is very common to non-metals and some metalloids. Silicon is a metalloid and Cobalt is a metal. Metals show a high degree of plasticity as compared to non-metals and metalloids. Plasticity is a mechanical property of a material to be deformed without breaking.

Answer two atoms of oxygen;

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
