Transition Elements from the Left Side of the Periodic Table

question 5

Multiple Choice

Transition elements from the left side of the periodic table are generally found as

• A)sulfides because they tend to give up bonding electrons and form crystals with high lattice energies with sulfur.
• B)sulfides because their electronegativities favor formation of covalent bonds with the polarizable sulfide anion.
• C)oxides because they tend to give up bonding electrons and form crystals with high lattice energies with oxygen.
• D)oxides because oxygen, with its high electronegativity, forms strong covalent bonds with them.
• E)the uncombined elements, because they are noble metals.

Definitions:

Spinal Cord

A long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column, playing a critical role in transmitting neural signals between the brain and the rest of the body.

Sympathetic Nerve Fibers

Nerve fibers that are part of the sympathetic nervous system, involved in the body's fight or flight response by activating bodily systems.

Parasympathetic Nerve Fibers

Components of the autonomic nervous system that help the body to relax and conserve energy, often referred to as the "rest and digest" system.

Nervous System

A complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.
