Diagrams
According to the Lewis Dot structure, how many electrons does Oxygen need to have a stable valence shell? (see slide 1)
2
How does the Periodic Table organize atoms of elements with the same number of valence electrons? (see periodic table)
In vertical groups/columns
What are valence electrons?
electrons in the outermost shell of an atom
occurs between a metal and nonmetal
ionic bond
This type of bond has a one pair of shared electrons
single covalent
According to the Lewis Dot structure, how many electrons does Flourine need to have a stable valence shell? (see slide 3)
1
How does the Periodic Table organize atoms of elements with the same number of electron shells? (see periodic table)
In periods/rows
What will an atom do if it has 1-3 valence electrons?
Try to donate/get rid of them
occurs between two or more nonmetals
covalent bond
This type of bond has a two pairs of shared electrons
double covalent
As electron shells move outward (radius increases) does the electron energy increase or decrease? (see slide 5)
It increases; more space between electrons and they're farther from the nucleus
Why do Sodium and Chlorine easily form an ionic bond? (see periodic table)
Sodium (a metal) has 1 valence electron to donate to Chlorine's (a nonmetal) 7 valence electrons to create a stable 8-electron valence shell
What will an atom do if it has 5-7 valence electrons?
Try to gain electrons
Is H2O formed from a covalent or ionic bond?
Covalent; has two nonmetals
a metal donates electrons to a nonmetal in this kind of bond
Ionic
How many valence electrons is the magic number that atoms are trying to seek in order to stabilize?
8
Is NaCl (sodium chloride) formed from an ionic or covalent bond?
Ionic; metal and nonmetal
two nonmetals share electrons in this kind of bond
covalent
Hydrogen Chloride is an example of what kind of bond?
Covalent; two nonmetals
