We won’t be able to describe because we can’t see it
The periodic table contains groups and periods that include the elements. For group 1 metal lithium is least likely to lose an electron.
<h3>What are group 1 metals?</h3>
Group 1 metals are the alkali metals that include, Li, Na, K, Rb, and Cs. They show the property exhibited by the metals. The chemical trends of group 1 show that cesium loses an electron more easily than the other elements.
When going down the group the tendency to lose electrons increases as the atomic radius increases. The electron gets far away from the nucleus making it easy to get removed.
Therefore, lithium being the first element of the group has the smallest radii and is least likely to lose an electron.

The answers to the questions are as follows;
- It would gain three electrons
- The difference in their electronegativities.
- The elements have filled Valence levels
- potassium (K) with a 1+ charge
- ClO-
Question 1:
- How would the electron configuration of nitrogen change to make a stable configuration?
Since Nitrogen has 5 Valence electrons, it needs 3 electrons to attain it's octet configuration. As such, it gains 3 electrons.
Question 2:
- Which quantity determines how two atoms bond.
The quantity which determines how two atoms bond is The difference in their electronegativities.
Question 3:
- Which statement best explains why the elements in Group 18 do not have electronegativity values.
This is because the elements have filled Valence levels.
Question 4:
- Based on patterns in the periodic table, which ion has a stable valence electron configuration
The ion which has a stable Valence electron configuration is potassium (K) with a 1+ charge
Question 5;
- Which chemical formula represents a polyatomic ion?
The chemical formula which represents a polyatomic ion is; ClO-
Answer:
Modern periodic law
Explanation:
There are many ways of stating the modern periodic law. Generally, the modern periodic law states that the properties of elements are a periodic function of their atomic numbers. That means, similar properties recur periodically when elements are arranged according to increasing atomic number.
Two scientists were largely responsible for our present day understanding of the modern periodic law, they are, Mendeleev and Moseley. Their work laid the foundation for the periodic table in its current form.
