Dominant: the more common trait (brown hair)
Recessive: a trait that doesn't show up unless both parents carry it (blue eyes)
Co- dominant: both traits show up and co- exist (AB blood)
Incomplete dominance: when a dominant gene does not completely mask a recessive gene so they blend (pink flower)
Phenotype: physical trait- able to be seen (stripes on a zebra)
Genotype: genetic makeup of an organism - genetic trait
Hetrozygous: different (Bb)
Homzygous dominant: same and dominant (bb) and (BB)
Purebred: same as homzygous- has same alleles (bb) and (BB)
Hybrid: also known as heterozygous traits

The alkali metals in group l of the periodic table all have a single electron in the outermost shell. These metals form covalent bonds with for example the halogens, which have 7 electrons in their outer shell.
When the alkali metal halide, such as KCl is dissolved in water, it dissociates into ions. The K atom loses the single electron, and therefore has a positive charge. In turn, the chloride atom gains the electron and becomes the negatively charged chloride ion.
