Q: Name the group that has a general electron configuration of ns^2 and provide an example of an atom with this general configuration.
A: Alkaline Earth Metals and Beryllium [He] 2s^2
Q: Name the group that has a general electron configuration of ns^2np^6 and provide an example of an atom with this general configuration.
A: Noble Gases Neon [He] 2s^2 2p^6
I think you are on the right track but I don't think you've answered the question. For #1, Be is H 2s2 but the alkaline earth metals are not that but Ne 2s2 or Ar 2s2 etc. I think the questions is asking for the GROUP so I would answer group IIA
See my notes on #1. For #2 I would write group VIII
To find the answer to the question, you need to know the general electron configurations of different groups of elements in the periodic table. Let's break it down:
- The first question asks for a group with a general electron configuration of ns^2. This indicates that the outermost energy level of the atoms in this group has two electrons in the s sublevel. The group that fits this description is the Alkaline Earth Metals, which are found in Group 2 of the periodic table. An example of an atom with this general configuration is Beryllium (Be), whose electron configuration is [He] 2s^2.
- For the second question, it asks for a group with a general electron configuration of ns^2np^6. This means that the outermost energy level of the atoms in this group has two electrons in the s sublevel and six electrons in the p sublevel. The group that fits this description is the Noble Gases, also known as Group 18 or Group 8A. An example of an atom with this general configuration is Neon (Ne), whose electron configuration is [He] 2s^2 2p^6.
Remember that the periodic table is organized in a way that elements with similar electron configurations are grouped together. By understanding the patterns of electron configurations, you can determine the group and find examples within that group.
