Answer:
okay so i hope this helps
Explanation:
In chemistry and physics, the atomic theory explains how our understanding of the atom has changed over time. Atoms were once thought to be the smallest pieces of matter. However, it is now known that atoms are made up of protons, neutrons, and electrons. These subatomic particles are made up of quarks.
Answer:
• Hydrogen and oxygen atoms
Explanation:
Hydrogen and oxygen are nonmetals. They are most likely to share electrons and form a covalent bond.
A is wrong. Gold is a metal, so it will form metallic bonds.
O is wrong. Neon is a noble gas. It has a complete octet, so it is unlikely to form covalent bonds.
D is wrong. Mg is a metal, and Br is a nonmetal. They are more likely to form ionic bonds.
A unit of ppm has an acronym of parts per million. The
equivalent units of ppm is therefore mg/L and mg/kg. So the ppm is:
mass Ca+ = 1.3 g = 1300 mg
ppm = 1300 mg / 3100 kg
<span>ppm = 0.42 ppm</span>
