Answer:
group 16 period 2 of the periodic table
note: that is not the electronic configuration, that is the Bohr model.
Answer:
Carbon is bigger
Explanation:
There are twice as many number of hydrogen-to-oxygen atoms. This applies to carbon atoms as well when compared to hydrogen atoms.
Well you have to do it because nobody on here has the answer choices but you
Answer:
He's flying and was looking
Explanation:
Reactivity - Reactivity refers to how likely or vigorously an atom is to react with other substances. This is usually determined by how easily electrons can be removed (ionization energy) and how badly they want to take other atom's electrons (electronegativity) because it is the transfer/interaction of electrons that is the basis of chemical reactions.
Metals
Period - reactivity decreases as you go from left to right across a period.
Group - reactivity increases as you go down a group
Why? The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.
Non-metals
Period - reactivity increases as you go from the left to the right across a period.
Group - reactivity decreases as you go down the group.
Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron
