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-
The only chemical that is a liquid at room temperature is Mercury. It's toxic, and has a high vapor pressure at room temperature.
Answer:
Explanation:
A is Magnesium, B is Aluminium both are adjacent element and lie in third period.
Magnesium with atomic number of 12 consist two s electrons in it's valence shell in ground state whereas, Aluminium which has atomic number of 13 consist three electrons in it's valence shell in the ground state out of which two are s electrons and only one p electron.
Answer:
Matter:
toothpaste
gasoline
bacteria
cell
Not matter:
happiness
sound
Explanation:
Matter is something that has mass and volume. Happiness is just a feeling, it doesn't exist in 3d world. Sound is a wave or just the movement of matter (particles of matter). Others have masses and volumes.
