Answer:
The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. ... This means that they have more collisions with each other and the sides of the container and hence the pressure is increased.
this would be the best one to use
hope this helps :)
The elements are identified by its aomic number and they are placed in the periodic table in ascending order of atomic number.
There is one unique element for a given atomic number.
For example, atomic number 1 identifies Hydrogen and there cannot be another different element with the same atomic number.
All the elements with atomic numbers from 1 to 118 have been discovered. So, you know that there is not room for new products with atomic number equal or less than 118.
Hey there!
Your correct answer will be B., D.
The reason that A. and C. are not true is this:
For A.: Electronegativity gets higher as you move up and to the right on the periodic table. This means that, generally, the bigger molecules have a <em>smaller </em>electronegativity number.
For C.: This is simply the reverse of the correct statement. Ionization energy is the energy to <em>take away </em>a(n) electron(s) of an atom.
I hope this helps!
