Answer:
<em><u>Intermolecular forces determine bulk properties, such as the melting points of solids and the boiling points of liquids. Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.</u></em>
Jupiter looks as if it has stripes, thanks to the gas that surrounds it :)
Answer:
The correct option is B
Explanation:
One of the claims of John Dalton's atomic theory is that atom is the smallest unit of matter (which suggests that there are no particles smaller than an atom in any matter). This claim has been disproved by the modern atomic theory which established that there are particles smaller than atom (called subatomic particles). These particles are electrons, protons and neutrons.
One of the modern atomic theory was by Neils Bohr, who proposed that <u>electrons move in circular orbits around the central nucleus</u>. Thus, the electrons of iron can also be said to be present in a region of space (circular path) around the nucleus. This proves that option B is the correct option as John Dalton's theory did not even recognize the electron(s) nor the nucleus.
Polar covalent because it is 2 nonmetals and the molecule has a net dipole movement.
An ion must be shaped when a neutral atom picks up or loses electrons.
Since electrons convey a negative charge, picking up electrons will bring about the formation of a contrarily charged ion, or anion. Thus, losing electrons will bring about the formation of an emphatically charged ion, or cation.
For your situation, the sulfide anion, S^2−1, conveys a(2−) negative charge, which must imply that it picked up electrons.
All the more particularly, it picked up 2 electrons. A neutral sulfur atom has an atomic number equivalent to 16, which implies that it has 16 protons inside its nucleus and 16 electrons encompassing its nucleus.
For every electron picked up, the ion's general charge diminishes by 1 unit, which additionally affirms the way that the unbiased sulfur atom picked up 2 electrons to get the (2−) charge.
