Atom Components
What is the charge of a proton?
What do elements in the same period have in common?
Same # of shells
An element loses an electron and becomes more positive. What kind of element would it be attracted to?
a negative element or anion
Electrons in the outermost shell
valence
Draw a Bohr model of magnesium (Mg)
12 electrons - 2, 8, 2
Which two subatomic particles are located in the nucleus?
protons & neutrons
What do elements in the same group/family have in common?
An element with 7 valence electrons bonds to an element with 1 valence electron by sharing 1 electron between them. What type of bond is this? Covalent or ionic?
covalent
Shiny, malleable and ductile - metalloid, nonmetal or metal?
metal
Draw a Lewis Dot for potassium (K)
K with 1 dot
Where are electrons located in an atom?
On the orbits/cloud/shells
Name 1 element that would react the same as Carbon and why.
Silicon, Germanium, Tin, Lead, Flerovium
Same group = same valence e-
Based on its valence electrons, how many bonds does carbon want?
4
How many electrons fit in each shell?
2,8,8
How many protons, neutrons, and electrons does Hydrogen (H) have?
P=1, N=0, E=1
What determines the # of protons in an element?
Atomic number
How many more protons does oxygen have than carbon?
2
A sodium ion that is positive is attracted to a chloride ion that is negative. What type of bond is this?
ionic
A negative ion
anion
Does Neon want to bond? Explain why or why not.
No- full outer shell
Protons and Neutrons 1amu, electrons 0 amu
Calcium has 2 valence e-'s. Which of these would also have 2? (Radium, Barium, Strontium, Magnesium)
All of them have 2 (all in same group)
If lithium (Li) bonds ionically to Chlorine (Cl), what would be the ions formed as a result?
Li1+ and Cl1-
A positive ion
cation
Atomic mass is 88 and has 50 neutrons. How many shells do I need?
5
