Which statement below accurately describes the atoms of a specific element?An antimony, Sb, atom contains 122 protons inside the nucleus and 51 neutrons outside the nucleus. A manganese, Mn, atom contains 55 electrons outside the nucleus and 25 neutrons inside the nucleus. A chlorine, Cl, atom contains 35 electrons and 27 protons inside the nucleus. An arsenic, As, atom contains 33 protons inside the nucleus and 33 electrons outside the nucleus.

An arsenic, As, atom contains 33 protons inside the nucleus and 33 electrons outside the nucleus.

Explanation:

The protons are positively charged, electrons are negatively charged and neutrons has no charge (neutral).  The protons and neutrons are present inside the nucleus and the electrons are located outside the nucleus.

Antimony (Sb) has an atomic number of 51 and thus contains 51 electrons and 51 protons. It has a mass number of 121 and thus conatins 70 neutrons.

Manganese (Mn) has an atomic number of 25 and thus contains 25 electrons and 25 protons.

Chlorine (Cl) has an atomic number of 17 and thus contains 17 electrons and 17 protons.

Arsenic (As) has an atomic number of 33 and thus contains 33 electrons and 33 protons.

the temperature of the gas, in k, not celsius.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
