Atoms
The three subatomic particles within an atom.
What are Protons, Neutrons, and Electrons?
This is the NAME of the isotope that has 12 protons and 15 neutrons.
What is Magnesium - 27?
This is the charge on a Strontium ion.
What is +2?
Carbon-12 and Carbon- 13 have this in common.
What is they have the same number of protons (atomic number).. (Same number of electrons OK too)
Group 13 elements have this many valence electrons.
What is 3 valence electrons?
Protons are located here.
What is the nucleus?
This is the ATOMIC NUMBER of an isotope with 20 protons, 20 electrons, and 20 neutrons.
What is an atomic number of 20?
This is the TYPE (not charge) of ion that Oxygen forms.
What is an ANION?
From its name, what do you know about Oxygen-22?
Its mass number is 22.
It must have 14 neutrons.
Xenon has this many valence electrons.
What is 8 valence electrons?
Electrons are located here.
What are energy levels?
This is the ATOMIC MASS of the isotope C-14.
What is is an atomic mass = 14.
Does Phosphorus gain or lose electron(s) when it forms an ion?
What is "gain electrons"?
Describe the relationship between protons and the atomic number.
They are the same numbers
If a group 15 element gains 3 electrons, it will now contain this many valence electrons.
What is 8 valence electrons?
This is how atomic mass is calculated.
What is protons plus neutrons?
This is the number of ELECTRONS in the isotope Hydrogen-2.
What is 1 electron?
This is what the PERIOD number on the periodic table tells us.
What is the number of energy levels?
If you know the atomic number and the atomic mass of an isotope, how do you calculate the number of NEUTRONS?
Mass # - Atomic # = neutrons
Elements in this family form more than one ion.
What is the transition metals?
These are the smallest subatomic particle.
What are electrons.
This is the definition of an ISOTOPE.
What are atoms of the SAME ELEMENT with DIFFERENT numbers of NEUTRONS?
The Alkaline Earth Metals form ions with this charge.
What is a +2 charge?
Which elements within a group are the most reactive?
Elements in higher Periods are more reactive.
What happens to the nucleus of an atom as you move from right to left in a single period on the periodic table?
The atomic mass increases
or
The atomic number increases
