What is Nobel gases
What is Flourine
This is the reaction between an acid and a base.
What is neutralization.
This is why it is more difficult to observe the presence of neutrons in an atom.
What is neutrons are held tightly in the nucleus and do not react with other charges.
Name two elements, one metalloid and one metal, also which element would have a lower boiling point.
Metalloids have a lower boiling point.
Use the periodic table to determine the number of valence electrons in H and I, the draw a dot diagram showing the polar covalent bond they form.
..
H : I :
..
This is how a base feels
What is slippery
In Rutherford's experiment, why would it be more difficult to detect the release of neutrons compared to protons?
The detector (foil) would respond to positive charge not a neutral charge
