Where are Protons located inside an Atom?
Nucleus
Where are Neutrons located inside an Atom?
Nucleus
Where are Electrons located in an Atom?
In Electron Shells surrounding the Nucleus.
When looking at the Periodic Table, the Electron Shells are represented by ____________. (columns or rows?)
Rows
You are drawing the Bohr Diagram for an Atom of the Element Zinc. How many Electron Shells does this Atom have?
4 Electron Shells
The number of Protons in an Atom is equivalent to the Atom's ___________________.
Atomic Number
True or False? The number of Neutrons an Atom has is equivalent to that Element's Average Atomic Mass (AAM).
False. You must round the AAM to the nearest whole number, then subtract the Atomic # to get the #Neutrons.
True or False? Valence Electrons (VE) are located in the furthest Electron Shell away from the Nucleus in an Atom.
True
On the Periodic Table, each box represents 1 ____________ in an Atom.
You are drawing the Bohr Diagram for an Atom of the Element Bromine. How many Valence Electrons (VE) does this Atom have?
7 VE
How many protons does an Atom of the Element Iron have?
26
An Atom of an Element has an Atomic Number of 86 and an Average Atomic Mass of 222. How many Neutrons does this Atom have?
222 - 86 = 136
An Atom of an Element has an Atomic Number of 43 and an Average Atomic Mass of 98. How many Electrons does this Atom have? (Consider that the atom is electrically neutral)
