Dull, Luster, Brittle (break apart), do not reflect much light.
Do all elements in the periodic table have the same number er of atomic orbitals?
Elements on the periodic table do have the same number of atomic orbitals.
When are covalent bonds formed?
Covalent bonds are formed when atoms share electrons.
What is an Ion? How do you know if its a positive Ion or negative Ion?
a charged atom with the same number of protons but different number of electrons. Positive Ion (Lose electrons) Negative Ion (Gain electrons)
In an isotope (Hydrogen-2) how many protons, neutrons, and electrons are in it?
What is one of the physical properties used to distinguish between the three groups?
Luster = The ability of a substance to reflect light.
Conductivity = The ability of the substance to conduct electricity that can be tested with a conductivity meter.
Malleability = The ability of the substance to be hammered into sheets without breaking
Ductility = The ability of the substance to be pulled into a thin wire.
How do you know if elements will have something in common?
How are Ionic Bonds formed?
Ionic Bonds are formed when opposibly charged ions are attracted to each other.
