15 Questions
Why does electronegativity decrease down a group on the periodic table?
The presence of more electron shells between the nucleus and the outermost electrons.
How does the number of electron shells affect nuclear shielding?
More electron shells increase shielding.
Why do noble gases have electronegativity values of 0.0?
Because they have full outer shells of electrons.
In what scenario are nonpolar molecules formed?
When carbon bonds with hydrogen.
How is the polarity of the amide group utilized in drug manufacturing?
To make drugs soluble and more effective.
Why do elements with atomic numbers greater than 104 have electronegativity values of 0.0?
Because their nucleus is unstable and breaks down.
What effect does having more electron shells between the nucleus and outermost electrons have on electronegativity?
It decreases electronegativity.
Why do Francium's outermost electrons get easily pulled away from its nucleus?
Due to the low number of electron shells between the nucleus and outermost electrons.
What is the reason behind nonpolar and polar substances not mixing well?
Their different polarities make them repel each other.
What factor contributes to the low or nonexistent level of nuclear shielding in an atom?
The presence of more electron shells between the nucleus and the outer shell electrons
Which element is likely to have the lowest electronegativity value?
Francium
Why do noble gases typically have an electronegativity value of 0.0?
Their atoms have full outer electron shells
What characteristic makes molecules with a C-H bond nonpolar?
Similar electronegativities of carbon and hydrogen
What effect does moving down a group on the periodic table have on the electronegativity of elements?
Decreases electronegativity
Which atoms bond together to form an amide bond that joins amino acids in proteins?
Carbon and nitrogen
