This property of bromine could NOT be predicted based on the fact that it is a nonmetal in the halogen family.
What is it is a liquid at room temperature?
100
This is what can be said about elements in the same row of the periodic table.
What is they have properties that change in a predictable pattern?
100
This is what scientists do in order to study very small things such as atoms.
What is create models to describe them?
100
Isotopes of the same element must have different numbers of this.
What is neutrons?
100
True or False: In general, metals have a wide range of chemical properties.
What is True?
200
The elements of this family do not ordinarily form compounds.
What is noble gases?
200
From an element's location in the periodic table, you can predict this.
What is its properties?
200
These parts of the atom move around the nucleus.
What is electrons?
200
This is how many neutrons Carbon-14 has.
What is 8?
200
All elements are composed of this extremely small particle.
What is atoms?
300
These are the most chemically reactive metals of the periodic table.
What is group 1, alkali metals?
300
Mendeleev created the first periodic table by arranging elements in order of this.
What is increasing atomic mass?
300
These are the particles in an atom that have a negative charge.
What is electrons?
300
Because isotopes vary in their number of neutrons, they also have different_________.
What is atomic masses?
300
The atomic number of an element is based on this.
What is the number of protons in its nucleus?
400
This is the element that is located in the first row of group 1, and why it is not included in group 1.
What is Hydrogen? It is the "weirdo" because it is not a metal (i.e. gas) and chemically very different from the rest of the elements in group 1.
400
Nonmetals can be found on this side of the periodic table.
What is the right side?
400
These subatomic particles have no charge, they are neutral.
What is the neutron?
400
This is the component of isotope notation that specifies its name/identity.
What is the symbol?
400
True or False: Atoms of different elements are the same.
What is false?
500
This is why iron and certain other transition metals are used in construction instead of the alkali metals.
What is alkali metals are extremely reactive, therefore using a transition metal that will not degrade or react with oxygen in the air or other aspects of nature will be structurally more stable and adequate for construction?
500
This is the state of matter the element in group 18, period 4 will be.
What is a gas?
500
This property of an element indicates the number of protons in its atoms.
What is the atomic number?
500
This is the location of where neutrons and protons are found in atoms.
What is the nucleus?
500
At room temperature, all the metalloids are solids, while most nonmetals are this state of matter.
What is gases?
