Respuesta :
Changes observed from the reactivity of the elements are;
- Reactivity increases
- Sodium has more shell
- Valence electrons in sodium are farther from the nucleus
- Atomic number 11 does not have a full electron shell
What is reactivity of elements in the periodic table?
Reactivity is a measure of how easily an element will combine with other elements to form compounds.
An element with atomic number of 11 is known as Sodium, found in group 1 of the periodic table with is the group of most reactive metals in the periodic table.
An element with atomic number of 10 is known as neon, found in group 8 of the periodic table and it is known as inert gas because it has octet structure.
Thus, we can conclude the following;
- Reactivity increases
- Sodium has more shell
- Valence electrons in sodium are farther from the nucleus
- Atomic number 11 does not have a full electron shell
