Answer:
- 53 protons
- 131g
- Iodine
- Halogens
Explanation:
atomic no. = no. of protons
= 53 proton
mass = no. of protons + no. of
neutrons
= 53 + 78
= 131
And the answer is equivalent to 0.64 moles of CO2.

Answer:
In an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus. If there are more electrons than protons, the atom has a negative charge. If there are fewer electrons than protons, the atom has a positive charge.
Explanation:
Answer:86
Explanation: to find atomic mass you take the number of protons and the number of neutrons. therefore you take the 40 protons and the 46 neutrons to find the mass. :)
