Here, we are required to determine how many electrons are typically involved in bonding for group 1, group 2 and group 3 elements and How many electrons are typically involved in bonding for group 6, 7 and 8 elements.
- For group 1: Only one electron.
- For group 2: Only two electrons
- For group 3: Only 3 electrons
- For group 6: Only 2 electrons
- Fir group 7: Only 1 electron
- For group 8: No electron
<em>The Valence electrons are the electrons which are available for bonding and chemical reactions in elements.</em>
<em>The Valence electrons are the electrons which are available for bonding and chemical reactions in elements.However, not all Valence electrons are actively involved in bonding. This is evident in the group 7(halogens) elements, although they have 7 Valence electrons, only one is actively involved in bonding.</em>
- For group 1 elements: They have only one Valence electron and it is actively involved in bonding (ionic bonding)
- For group 2 elements: They have only two Valence electron and both are actively involved in bonding (ionic bonding)
- For group 3 elements: They have only three Valence electrons and all three are typically used for bonding.
- For group 6 elements: They have 6 Valence electrons and are electronegative. As such, they only need to receive 2 electrons from an electropositive element and consequently, they only contribute two electrons into the bonding. As such, only 2 electrons are typically used for bonding.
- For group 7: They have 7 Valence electrons and are highly electronegative. As such, they only need to receive 1 electrons from an electropositive element and consequently, they only contribute 1 electrons into the bonding. As such, only 1 electrons are typically used for bonding.
- For group 8: They have a full octet configuration and are unreactive. Therefore, no electron is typically used for bonding.

Answer:
D
Explanation:
Shortest Day of the Year in the Northern Hemisphere. The December solstice can be on December 20, 21, 22, or 23. The North Pole is tilted furthest from the Sun. It is the winter solstice in the Northern Hemisphere, where it is the darkest day of the year.
Answer:
Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combines with oxygen in the air to form carbon dioxide and water vapor.

Your welcome easy.
Kinetic energy of an object is directly connected to the speed object. Like a toy car being used on a table, the toy car will speed up which means the kinetic energy of that toy car will also increase
Answer:
Value for K would be too small. Less AgCl would dissolve due to the common ion effect due to the presence of Cl- in the water.
Explanation:
Think of this through the lenses of a shifting problem. Cl- ions are a product in this situation and increasing its concentration would shift the reaction back to the solid AgCl. In this specific case, due to Cl- ions, AgCl would dissolve less to maintain equilibrium and as a result, the concentrations of Ag+ and Cl- ions would be lower than normal making a smaller K value.
