Answer:
nstead of using two dots to indicate the two electrons that comprise the covalent bond, a line is substituted for the two dots that represent the two electrons. Below is shown the Lewis structure for water. Two hydrogens (H) are separately covalently bonded to the central oxygen (O) atom.
Explanation:
Answer:
A) the charge on the ion of X
Explanation:
All group 3 elements have a charge of positive three
Temperature
A measure of kinetic energy of particle motion within a substance is temperature.
From our knowledge of periodic trends, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.
<h3>Periodic trends</h3>
The periodic trends are those properties that increase or decrease down the group or across the period. These periodic trends include;
- Ionization energy
- Electron affinity
- Atomic radius
- Ionic radius etc
As more shell are added down the group in group 14, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.
