Understanding electron configurations & the periodic table

Three elements are listed below. How many electrons does each have in its outermost electron shell? (1) aluminum (2) krypton (3) potassium

The first ionization energy for Mg (738 kJ/mol) is higher than that for Na (469 kJ/mol) but the second ionization energy for Na (4562 kJ/mol) is much larger than that for Mg (1451 kJ/mol). Explain this observation.

See the attached file. Consider the Na atom. Although the ground state of Na atom has one and only one corresponding electron configuration, other electron configurations are certainly possible for Na atom; they correspond to higher-lying excited electronic states. The table below gives some of the possible electron configura

The general electron configuration for atoms of all elements in Group 5A is ________. ns2np6 ns2np5 ns2np4 ns2np3 ns2np1 -------------------------------------------------------------------------------- Which element has the following electron configuration? [Kr]5s24d105p1 Sn Sb Cd Ga In ------

Write the electron configurations for Mg and Ar, using both the spdf notation and orbital box diagrams. Describe the relation of the atom's electron configuration to its position in the periodic table. electron configuration for Mg___________ spdf____________________ orbital box diagram: electron configuration for A

Describe the patterns in the electronic configurations of the elements. Each row across the periodic table is called a period and the elements gradually change properties from left to right. Can you explain this in terms of the electronic configurations? Each column of the periodic table is called a family. Elements in t

What will be the likely charges of elements with an electron arrangement of 2,8,8,2 and an element with an electron arrangement of 2,8,18,7 when they form ions?

Parallel Exercises An electron with a mass of 9.11x10-31 kg has a velocity of 4.3 106 in the innermost orbit of a hydrogen atom. What is the de Broglie Wavelength of the electron? An electron wave making a standing wave in hydrogen atom has a wavelength of 8.33 x 10-11 m. If the mass of the electron is 9.11x10-31 kg. what
