100
3 basic parts of atom and charges
What is proton (+1), electron (-1), and neutron (0)
100
What is the atomic number? What is the mass number?
Number of protons, number of protons and neutrons
100
What are the two types of bonds? Explain them
Covalent - sharing electrons Ionic- transfer of electrons
200
Foolproof way to identify element
What is atomic number (number of protons)?
200
What element has 9 protons and 9 electrons? What element has 9 protons and 10 electrons?
Flourine
200
What is the octet rule? Which elements already have "this"?
Atoms want a full outer shell, normally 8 electrons in it. Noble gases
300
What is an isotope
Same element, different number of neutrons
300
Number of protons, neutrons, and electrons
17 p, 18 n, 18 e
300
What is a mole? Why is it useful?
Quantity. A useable measurement for tiny atoms
400
What is an ion? What determines if an element is an ion (think atomic particles)?
Atom or molecule with a charge, electrons
400
How many protons, neutrons, and electrons? What is the element?
6 p, 6 n, 6 e, carbon
400
What is an element? What is a compound?
Elements are pure- only 1 type of atom. Compounds are different atoms bonded together.
500
What are valence electrons? Why are they important?
Outermost electrons, determine reactivity
500
Number of protons, neutrons, and electrons
16 p, 16 n, 18 e
500
Why is this element unlikely to appear? Xe +1
Noble gases are stable. They don't normally exist as ions.
