Question

A) An atom's size is determined by how far the outermost electrons are from the nucleus. The size of an atom is affected by the size of an atom's orbitals as well as by the positive pull of an atom's protons. Arrange the following elements in order of decreasing atomic size. Rank the atoms from largest to smallest. To rank items as equivalent, overlap them. Na, B, Ne, F, N. B) The ionization energy of an atom is the energy required to remove an electron from the atom in the gaseous state. Arrange the following elements in order of decreasing ionization energy. Rank from highest to lowest ionization energy. To rank items as equivalent, overlap them. Manganese, Silicon, Barium, Oxygen, and Nickel.

Answer 1

Part 1)

Rank the atoms from largest to smallest. To rank items as equivalent, overlap them. Na, B, Ne, F, N. B

Na (190 pm)> B (87 pm) > N (56 pm) > F (42 pm) Ne (38 pm)

Part 2)

Rank from highest to lowest ionization energy. To rank items as equivalent, overlap them. Manganese, Silicon, Barium, Oxygen, and Nickel.

Oxygen (1313.9 KJ/mol)

Silicon (786.5 KJ/mol)

Nickel (737.1 KJ/mol)

Manganese (652.9 KJ/mol)

Barium (502.9 KJ/mol)

Oxygen > Silicon > Nickel > Manganese > Barium
