Burning is a chemical reaction
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-
Explanation:
the volume and temperature of a gas have a ditect relationship,as the temperature increases the volume also increases when pressure is held constand, heating the gas increases the kinetic energy of the particles or atoms,causing the gas to expand until the pressure returns to its original value
In Thomson's experiment, he showed that an electrical current can be made to flow from a positive site to a negative site.
