100
A property of a substance that could be measured or observed without changing its composition
What is physical properties
100
Major Contribution is The Atom
What is Democritus
100
the process of particles being emitted from a nucleus as a result of nuclear instability
What is radioactivity
100
the number on the bottom of the symbol
What is the mass number
100
the bonding of oppositely charged ions
What is iconic bonding
200
Any change in a chemical composition that forms in a substance.
What is chemical change
200
who came up with the plum pudding model
What is J.J Thomson
200
the amount of time require for a decaying substance to lost half of its original amount
What is half life
200
the name of the vertical column and the horizontal column
What is vertical columns are called groups and horizontal rows are called periods
200
two types fo covalent bonds
What is polar covalent and non polar covalent
300
Anything that has mass and takes up space.
What is matter
300
who came up with the atomic theory
What is John Dalton
300
three main types of radioactive decay
What is beta decay alpha decay and gamma decay
300
a pattern observed on the periodic table for an atomic property
What is periodic trend
300
the difference between polar and non polar covalent bonds
What is Bonds are covalent bonds where electrons are shared unequally between atoms for polar covalent. Where electrons are shared equally between atoms for non polar covalent
400
The three states of matter and how the particles move
What is solids,particles vibrate in place. Liquids,particles slide past eachother. Gases,particles move fast with large spaces in between.
400
the elements of the atomic theory that were incorrect
What is All atoms of the given element are identical. Elements are composed of indivisible particles called atoms
400
what decay has the highest penetration and no mass or charge
What is gamma decay
400
four main periodic trends
What is atomic radius, ionization energy, electronegativity, and electron affinity
400
two properties of covalent compounds
What is forms longer bonds because bonds are weaker than ionic bonds and energy is lowered when atom form a covalent bond
500
The difference between physical change and chemical change.
What is chemical change has to have a chemical reaction to occur and any change that occur to a substance that does not change its chemical composition is physical change
500
the four principles of the atomic theory
What is Elements are composed of indivisble particles called atoms. All atoms of a given elements are identical. They are composed of atoms of one or more elements and wil form in only whole number ratios. A chemical reaction involves a combination,separation or rearrangement of atoms, not their creation or destruction.
500
the difference between nuclear fission and nuclear fusion
What is nuclear fission, is when the nucleus of the atom splits to form a more stable nucleus. Nuclear fusion, combines smaller nuclei into a larger one.
500
periodic trend explanation and group trend explanation
What is when comparing elements in the same period,compare the effective nuclear charges for periodic trend explanation. For group trend explanation compare the amount of electron shielding occuring in the same group
500
the order of increasing strength and length of chemical bonding and what should always go first
What is increasing strength is nonpolar covalent,polar covalent, and ionic. in order of increasing length, ionic, polar covalent and non polar covalent.metals should always go first
