This law states that any given compound will always contain the same relative number of atoms of its various elements.
What is the law of constant composition
100
This is the name given to the first family of elements.
What is Alkali metals
100
Isotopes will always have the same number of these two atomic particles.
What are protons and electrons.
100
This is the first element in the family that makes 3+ ions.
What is Boron
200
This is the most abundant element in the human body
What is carbon
200
This person elaborated on the law of constant composition and added four other rules to his theory.
Who is Dalton
200
The majority of elements on the periodic table including all that lie to the left of the staircase, have this in common.
What is they are metals
200
This is the what the abbreviation AMU stands for
What is atomic mass unit
200
This is the first element in the family that does not make ions but is also not a noble gas.
What is Carbon
300
This is how elements typically occur in nature
What is a mixture
300
In order for an element to have a neutral charge, these two particles must exist in equal quantities.
What are protons and electrons.
300
Elements that touch the staircase and maintain some but not all of the metallic properties are called this.
What is metalloid or semimetal
300
An element with an atomic number of 16 and mass number of 30 has this many neutrons
What is 14
300
A chloride ion will have this many protons.
What is 17
400
This is the term given to an element that typically exists as two atoms bonded together.
What is diatomic
400
This atomic particle has the greatest mass.
What is a neutron.
400
This is the only non-metal that does not reside to the right of the staircase.
What is hydrogen
400
This element has a mass number of 63 and 33 neutrons.
What is Zinc
400
An aluminum ion will have this many electrons.
What is 10
500
These three elements all exist naturally as diatomic molecules.
What are oxygen, hydrogen, nitrogen, fluorine, chlorine, bromine, iodine
500
Dalton's theory include five points
1. elements are made of atoms
2. all atoms of a given element are identical
3. atoms of a given element are different than atoms of any other element
4. atoms of one element can combine with atoms of another element to form compounds.
And this final point.
What is atoms cannot be created or destroyed in chemical reactions.
500
These are the four characteristics that make an element a metal.
What is luster, conduction, malleability, and ductility
500
In an element with Z=16 and 9 neutrons, this would be the value of A.
