Full Answer

Silicon belongs to the carbon family of elements, or group 14, in the periodic table. Although some of its chemical characteristics are unique and distinct from other group 14 elements, silicon exhibits the same bonding properties as carbon. Silicon can chemically combine with other atoms by sharing or losing its four valence electrons. However, silicon in solid form is generally non-reactive, particularly with water or oxygen. Due to its abundance on the earth's crust, silicon has several practical applications, including electronics, glass and ceramics manufacture and synthetic compounds production.

  • Q:

    How many valence electrons does palladium have?

    A:

    The element palladium has 10 valence electrons in its outermost shell, the 4d shell. Many elements follow the octet rule, where they are considered having a full outer shell when there are eight electrons. Transition metals and heavier elements are exceptions and are more stable when they have more electrons in their outer shell.

    How did nitrogen get its name?

    A:

    The chemical element, nitrogen, was formally named by the French chemist Jean-Antoine Claude Chaptal when he discovered that it is a primary component of potassium nitrate, also known as nitre. The name of nitrogen is derived from the combination of the two Greek words "nitron" and "genes," meaning niter forming.
