Laws and Theroms
Mass can't be created or destroyed, only broken and restructured
What is the law of conservation of mass?
JJ Thomson created this model of the atom based on this experiment with a cathode ray tube that proved charged particles.
What is the Plum pudding model?
This groups doesn't have electronegativity, and doesn't react.
What are the noble gases?
This is how much energy it takes for an atom to lose an electron and become an ion.
What is ionization energy?
Is Mr. K married?
yes
A given chemical compound always contain the same element in the exact same proportions by mass
This model was created with rings to describe different colors of light being reflected through a prism.
What is the Bohr Model?
This column contains the largest atoms with the lowest ionization energy.
What are the alkali metals?
This is how closely atoms hold on to themselves, and is repsonible for the size of the atoms.
What is eletronegitivity?
ew children, no
Two same elements form more than one compound, the different masses of one combine with the same mass of another element in the ratio of small whole numbers
What is the Law of Multiple Proportions?
This model formed electron clouds and further broke down the electron.
What is the quantum mechanics atom model?
This column is similar named to the one before it.
What are the alkaline earth metals?
As we go across this, the ionization energy and electronegativity increase.
What is a period? (rows)
Does Mr.K have a chemistry degree?
no for some reason
states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
What is Coulumb's Law?
These rings were like finger prints of certain atoms that reflected color.
What are spectral lines?
These elements vary in their ability to conduct electricity.
What are the metalloids or semi-metals?
This atoms is the smallest atom because of its high electronegativity and ionization energy.
What is Florine?
What pet does Mr.K have?
a cat
What is Coulumb's Law?
By comparing this, we can determine unknown elements.
What are an atom's spectrum?
This column contains the most highly dangerous and reactive elements.
What are the halogens?
These atoms do not have an electronegativity.
What is a noble gas?
Why do people like Mr. K?
give a good responce
