Mr. kawicki is teaching his sixth-grade science students about the scientific method. students are instructed about each component of the method first in order to understand the whole process. this instructional strategy is based on what concept?

This instructional strategy is based on bottom-up approach.

Explanation:

In this case, before teaching an experiment, the students are being trained about the components used in those experiments. This method of teaching will help students to learn the basic concepts and mechanisms of that experiment easily.

As they are learning about the components used in those experiments first, they can easily understand where is the problem occurring in case of any error. So, this type of approach of learning is termed as a bottom-up approach. Because the students are learning from the starting that is bottom and then they are making it as a whole experiment which is the up mechanism.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
