(a)
Interpretation:
The number of protons for the isotopes of tin that has mass numbers 116, 118 and 120 should be determined.
Concept Introduction:
The number of protons indicates the
(b)
Interpretation:
The number of neutrons for the isotopes of tin that has mass numbers 116, 118 and 120 should be determined.
Concept Introduction:
The number of neutrons along with number of protons indicates the mass number. The neutrons are neutrally charged particles and do not contribute to the charge of the atom on whole.
(c)
Interpretation:
The number of electrons for the isotopes of tin that has mass numbers as 116, 118 and 120 in its neutral state should be determined.
Concept Introduction:
The mass number is the total of number of protons and neutrons present in the nucleus. But it is also known that number of electrons is equal to the number of protons to keep the atom neutrally charged.
(d)
Interpretation:
The group number for the isotopes of tin that has mass numbers 116, 118 and 120 should be determined.
Concept Introduction:
The group number is indicated by the atomic number of the element. Atomic number is influenced by the number of protons in the nucleus.
(e)
Interpretation:
The symbol of the isotopes of tin that has mass numbers 116, 118 and 120 should be determined with its subscripts and superscripts.
Concept Introduction:
The isotope of any element is indicated by its atomic number and mass number. Both the numbers are displayed along with the element. The mass number is displayed as superscript while the atomic number is displayed as subscript as shown:

- From the following written description, write the balanced chemical equation for the reaction including state symbols. A diatomic gaseous molecule that contains 17 protons per atom is reacted with a solid element that has an atomic number of 19 to yield an ionic compound.arrow_forwardOne isotope of a metallic element has mass number 74 and has 51 neutrons in the nucleus. An atomic ion has 18 electrons. Write the symbol for this ion (give the symbol for the nucleus and give the ionic charge as a right superscript).arrow_forwardGive the complete symbol(ZAX), including atomic number and mass number, of (a) a nickel atom with 31 neutrons, (b) a plutonium atom with 150 neutrons, and (c) a tungsten atom with 110 neutrons.arrow_forward
- Given that the periodic table is an organizational scheme for the elements, what might be some other logical ways in which to group the elements that would provide meaningful chemical information in a periodic table of your own devising?arrow_forwardThough the common isotope of aluminum has a mass number of 27, isotopes of aluminum have been isolated (or prepared in nuclear reactors) with mass numbers of 24, 25, 26, 28, 29, and 30. How many neutrons are present in each of these isotopes? Why are they all considered aluminum atoms, even though they differ greatly in mass? Write the atomic symbol for each isotope.arrow_forwardGive the number of protons, electrons, and neutrons in neutral atoms of each of the following isotopes: 37Li 52125Te 47109Ag 715N 1531Parrow_forward
