Answer:
The isotope notation for an ion of silver-109 with a charge of positive 1 is .
Explanation:
The elements with same atomic number with different mass numbers are called isotopes.
The isotopes of silver is as follows.
From the above two isotopes have same atomic number and different mass number.
From the given,the isotope notation for an ion of silver-109 with a charge of positive 1
It can be represented is as follows.
General representation of isotope is as in attachment.
Answer:
Missing particles: (a positron) and an electron neutrino
.
The nuclear equation would be:
.
Explanation:
The mass number of a particle is the number on the top-right corner of its symbol.
The atomic number of a particle is the number on the lower-right corner of its symbol.
The nuclear reaction here resembles a beta-plus decay. The mass numbers of the two nuclei are equal. However, the atomic number of the product nucleus is lower than that of the reactant nucleus by .
A beta decay may either be a beta-plus decay or a beta-minus decay. In a beta-plus decay, a positively-charged positron and an electron neutrino
would be released. On the other hand, in a beta-minus decay, a negatively-charged electron
and an electron antineutrino
would be released.
Electric charge needs to be conserved in nuclear reactions, including this one.
The atomic number of the nucleus on the left-hand side is
, meaning that the nucleus has a charge of
. On the other hand, the atomic number of the
nucleus on the right-hand side shows that this nucleus carries a charge of only
.
By the conservation of electric charge, the particles on the right-hand side must carry a positive charge of . That rules out the possibility of the combination of one negatively-charged electron
(with a charge of
) and an electron antineutrino
(with no electric charge at all.)
Hence, the only possibility is that the missing particle is a positron (and an electron neutrino , which carries no electric charge.)
