(a)
Interpretation:
The symbol should be identified when the isotope contains
Concept introduction:
Atom:
Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons.
Atoms of different elements differ in the number of protons and electrons.
Isotope:
Isotopes are variants of a particular chemical element which differ in neutron number whereas protons number is same. Isotopes are same atomic number but different in the mass number.
The element symbol, atomic number and mass number can be written as follows,
A is Mass number (The total number of protons and neutrons in an atom) and it is written in the superscript.
Z is atomic number of the element and it is written in subscript.
X is the symbol of the element
(b)
Interpretation:
The symbol should be identified when the isotope contains
Concept introduction:
Atom:
Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons.
Atoms of different elements differ in the number of protons and electrons. Atomic number is equal to the number of protons in the nucleus of an atom and Mass number is the number of nucleons.

- An isotope of sodium (Na) has a mass number of 22. How many neutrons does it have? a. 11 b. 12 c. 22 d. 44arrow_forwardWhich element has only one proton?arrow_forwardPolonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po become after it emits an alpha particle?arrow_forward
- What enables a radioisotope to substitute for an ordinary (nonradioactive) atom of the same element molecule?arrow_forwardThe atomic mass number of an atom is determined by the sum of the number of in the atom.
