An element has a characteristic number of protons in the nucleus of its atoms. Whenever scientists find an atom with a different number of protons in the nucleus than of any known element, they know that they have discovered a new element.

What does the periodic table tell you about the element in a group?
The groups in the periodic table tell you what each element within them will react with, the number of valance electrons the element has, and what family it is in.
How could you tell if a sample of matter is an element?
Because it is a element that is a liquid at a room tempeture
How can you tell which group an element is in?
you have to look in the periods
What does reduction potential tell about the stability of an element?
The greater the reduction potential, the slower the element will oxidize.
What does electron configuration tell you about an element?
The electrons in an atom can tell you many things about the element such as: ~the atomic number ~number of valence electrons ~what column the element is in ex: Because if fluorine is element number 9 then there are 9 electrons.
How can you tell if iron is an element?
You can tell it is an element as it is on the periodic table, as Fe, in the transition metals block.
What do you notice about the location of all the element families on the periodic table tell you?
It can tell you crtain characteristics of that element.
What does the periodic table tell you about the element in a group?
The groups in the periodic table tell you what each element within them will react with, the number of valance electrons the element has, and what family it is in.
What does the mass of an element tell you about a molecule?
it tells you how much of the molecule the element is
Element's atomic number tell about that element?
The atomic number tells you the number of protons in the nucleus of that element.
Does the number of neutrons tell what element it is?
no
What does the mass percent of an element tell you about molecule?
it tells you how much of the molecule the element is
What does mass percent of an element tell you about a molecule?
it tells you how much of the molecule the element is
What does the atomic number of an element tell you about the element?
Atomic number = Number of protons
What does the period number tell about an element?
its tell you the atomics mass that occurs
How could you tell if an sample of matter is an element?
