Atoms, Elements, Compounds, and Chemical Bonds 1. The diagram below shows the atomic structures of two different atoms. Use the
diagram to:
• Assess the chemical properties of each atom in terms of stability or reactivity,
and explain your reasoning,
• Explain the relationship between atoms and elements. Be sure to refer to the
diagram in your explanation.

Whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
