How is mercury obtained and separated from other nearby substances?​
VLD [36.1K]

Answer:

Most mercury forms in a sulfide ore called cinnabar, but mercury is also frequently found in small amounts in other ores. A common method for separating mercury from cinnabar is to crush the ore and then heat it in a furnace in order to vaporize the mercury. This vapor is then condensed into liquid mercury form.

In an atom, the number of neutrons determines most specifically the ________.
lord [1]

In an atom, the number of neutrons determines most specifically the isotopes of an element.

<h2>Further Explanation</h2><h3>An atom  </h3>
  • An atom is defined as the smallest particle of an element that can take part in a chemical reaction.
  • Atoms are made of energy shells and the inner nucleus.
  • It is also made up of subatomic particles, protons and neutrons.
<h3>Neutrons  </h3>
  • They are sub-atomic particles in an atom that are found in the nucleus of an atom. They have a zero charge or no charge.
  • Neutrons are slightly heavier than protons.
  • The number of protons and neutrons in a nucleus of an atom results to the atomic mass number of an atom. Like protons they only take part in nuclear reactions.
<h3>Protons</h3>
  • Protons are subatomic particles that are found in the nucleus of an atom. They are positively charged. with a charge of +1.
  • The number of protons differ from one element to another and thus used as the atomic number of an individual element.
  • The nucleus of an atom is positively charged due to the positive charge of the protons.  
  • Additionally, protons do not take part in chemical reactions but in nuclear reactions.
<h3>Electrons  </h3>
  • They are found orbiting the nucleus on energy shells based on Clouds’ theory. Electrons are negatively charged each with a charge of -1.
  • The number of electrons and protons in a neutral atom are equal. Additionally they have the least mass of the three sub-atomic particles.
  • Electrons are the only sub-atomic particles that take part in chemical reactions.
<h3>Isotopes </h3>
  • Isotopes are atoms of the same element that have the same mass number but different atomic number.
<h3>Mass number;</h3>
  • Mass number is the sum of the number of protons and neutrons in the nucleus of an atom of an element.

Keywords: Atom, sub-atomic particles, electrons, protons, neutrons, isotopes
