Most of the mass of an atom is located in the (nucleus), and most of the volume is taken up by the (electron clouds).
The ones in the parenthesis are your answers.
Hope this helps!
<h2>Answer:</h2>
They would be arranged in a trigonal planar orientation.
<h3>Explanation:</h3>
If there were only three electron groups around an atom they tend to repel each other and gain a trigonal planar orientation. A molecule with three electron groups orients the three groups as far apart as possible. They adopt the positions of an equilateral triangle 120° apart and in a plane. The shape of such molecules is trigonal planar. An example is BF3:
Explanation:
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
When interaction between the solute and solvent are weak then solution will evaporate readily into the atmosphere. Therefore, it means vapor pressure increases with particularly weak solute-solvent interactions.
On the other hand, when interactions between the solute and solvent of a strong enough in a solution then vapors are not formed easily. This also means that vapor pressure decreases with particularly strong solute-solvent interactions.
Answer:
Ionic bonds form when atoms transfer electrons between each other, forming ions that are electrically attracted to each other forming a bond between them. Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion.
Explanation:
ionic bond
Because of the propensity of sodium to lose an electron and of chlorine to gain an electron, the elements are well suited to bond with one another. This transfer of electrons results in the formation of the ionic bond holding Na+ and Cl– together.
Answer:
It doesn't form ions. Hence, there is no charge and they are identified as molecules.
Explanation:
Molecular formula of water is H20. The decomposition of this molecule can be achieved by electrolysis, as follows
2H20 → 2H2 + O2
As the elements present in this molecule are not stable independently so they cannot exist in elemental form or as ions under normal conditions.
