An atom contains 8 protons, 8 neutrons and 10 electrons. A second atom contains 9 protons, 10 neutrons and 10 electrons. What can be said about
these two atoms?
A. Both atoms are neutral
B. The atoms are isotopes of each other
C. Both atoms are ions
D. these atoms cannot exist in nature

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

a polar bond is formed when electrons are shared unevenly between atoms

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
