The group number (in roman numerals) tells you what about the electronic configuration of an atom?
The outer shell electrons
How many electrons are there in the last shell of Silicon?
4
When subjected to stress, it fractures with little elastic deformation and without significant plastic deformation.
brittleness(Brittle)
The capability of being shaped or extended by hammering, forging, etc
Malleability(malleable)
It is a soft, silvery-white, highly reactive alkali metal , being in group 1 of the periodic table. It has only one stable isotope in nature The free metal does not occur in nature and must be prepared from compounds. This is a main component of the table salt
Sodium
It is a silvery-white metal that is soft enough to be cut with a knife with little force. This metal reacts rapidly with atmospheric oxygen to form flaky white peroxide in only seconds of exposure. It includes regulating fluid balance and controlling the electrical activity of the heart and other muscles.
Potasiium
t is a grey solid non-metal, that is used as an antiseptic chemical. This non-metal element has a unique physical property that doesn’t have a liquid state.
Iodine
It is a mineral that the body needs for growth and development. Your body uses this metal to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body, and myoglobin, a protein that provides oxygen to muscles. Its Latin name is Ferrum
Iron
It is an admixture of metals, or a metal combined with one or more other elements. For example, combining the metallic elements gold and copper produces red gold, gold and silver becomes white gold, and silver combined with copper produces sterling silver
