Which of the following has a full valence shell?
Oxygen
Helium
Hydrogen
Carbon
Why are we focusing on the elements H O N C ?
it's fun to misspell the word honk
they are the first 4 elements created after the Big Bang
they are only found on Earth
they make up the majority of the human body
Why are the atoms attached to Carbon, putting Carbon in the middle of this molecular structure
Carbon is magnetic
Carbon has the most mass, thus the most gravitational pull
Carbon is diamonds
Carbon can make up to 4 bonds, the most possible
Atoms "want" / strive to have...
A full outer shell of electrons
One electron short of a full shell
2 valence electrons
their time in the sun
Why can't Oxygen add one more Hydrogen to make H3O?
Mickey Mouse only has 2 ears
Hydrogen is very negatively charged
Oxygen can only form 2 bonds
How many molecules of water is this: 3H2O ? (write your answer as a number, not as a word)
