Groups, periods and blocks, electron shells, and the trends in electronegativity, atomic radius and ionisation energy.

Elements are in order of atomic number (protons). The period (row) is the number of electron shells; for the main groups the group (column) tells you the outer electrons, which is why elements in a group react alike. Every element also has its own page with its Bohr model, protons, neutrons and electron shells.

Animal vs wind pollination

	🐝 Animal	🌬 Wind
Petals	big, bright	small or none
Scent, nectar	yes	no
Anthers	inside	dangle out
Stigma	sticky	feathery
Pollen	sticky, less	light, lots

Pollination (anther → stigma) comes first. Fertilisation happens later, when the pollen tube reaches an ovule.
