Concept explainers
Interpretation:
All the elements in Group 3A should be identified. The relation between the designation of group and electronic configuration of all these elements should be explained.
Concept Introduction:
The electronic configuration of an atom represents the arrangement of electrons in the subshells and orbital shells. Generally. Electronic configuration is used to define the atom’s orbitals in its ground state.
Group 3A elements in the periodic table incorporates B (metalloid boron) and gallium (Ga), aluminum (Al), thallium (Tl) and indium (In). In group 3A boron basically forms covalent bond and the other elements of group 3A form ionic bond.

- 2-89 Assume that a new element has been discovered with atomic number 117. Its chemical properties should be similar to those of astatine (At). Predict whether the new element’s ionization energy will be greater than, the same as, or smaller than that of: (a)At (b)Raarrow_forward2-47 Which element in each pair is more metallic? (a) Silicon or aluminum (b) Arsenic or phosphorus (c) Gallium or germanium (d) Gallium or aluminumarrow_forward2-102 An element consists of 90.51% of an isotope with a mass of 19.992 amu, 0.27% of an isotope with a mass of 20.994 amu, and 9.22% of an isotope with a mass of 21.990 amu. Calculate the average atomic mass and identify the element.arrow_forward

To which two groups in the Periodic Table might this element belong?arrow_forward2-101 Complete the following table: Symbol Atomic number Atomic weight Mass number # of protons # of neutrons # of electrons H 0 Li 4 3 Al 26 58 78 17 20arrow_forward2-104 The average atomic weight of lithium is 6.941 amu. The two naturally occurring isotopes of lithium have the following masses: 6Li, 6.01512 amu; 7Li, 7.01600 amu. Calculate the percent abundance of 6Li and 7Li in naturally occurring lithium.arrow_forward
- 2-91 These are the first two ionization energy for lithium: Li(g) Li+(g) + e-(g) Ionization energy = 523 kJ/mol Li+(g) Li2+(g) + e-(g) Ionization energy = 7298 kJ/mol (a) Explain the large increase in ionization energy that occurs for the removal of the second electron. (b) The radius of Li is 78 pm (1 pm = 10-12 m) while that of a lithium atom, Li, is 152 pm. Exp lain why the radius of Li is so much smaller than the radius of Li.arrow_forward2-64 Consider the elements B, C, and N. Using only the Periodic Table, predict which of these three elements has: (a) the largest atomic radius. (b) the smallest atomic radius. (c) the largest ionization energy (d) the smallest ionization energyarrow_forward2.84 Early attempts to arrange the elements often focused on atomic weight. Mendeleev considered a number of properties in addition to atomic weight, so he realized that some elements seemed out of place when ordered by atomic weight. Using the modern periodic table, identify elements for which Mendeleev must have had to switch the order in order to get the correct sequence of elements.arrow_forward
