Which of the following Group 14 elements is a metal?
Lead is the only group 14 element that is metallic in both structure and properties under all conditions.
What are Group 14 elements explain?
Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).
What element has an atomic mass of 14?
Carbon-14: with 6 protons and 8 neutrons, and an atomic mass of 14.
Is silicon 14 an isotope?
Silicon (14Si) has 23 known isotopes, with mass numbers ranging from 22 to 44. Si (the most abundant isotope, at 92.23%), 29Si (4.67%), and 30Si (3.1%) are stable. The longest-lived radioisotope is 32Si, which is produced by cosmic ray spallation of argon.

The carbon family consists of one nonmetal (carbon), two metalloids (silicon and germanium), and two metals (tin and lead).
Where is group 14 on the periodic table?
The carbon group is a periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). It lies within the p-block. In modern IUPAC notation, it is called group 14.
Which of the following group 14 elements is a metal?
How many electrons does carbon 14 have?
Is silicone an element?
In short, silicon is a naturally occurring chemical element, whereas silicone is a synthetic substance. Silicon is the 14th element on the periodic table. It’s a metalloid, meaning it has properties of both metals and nonmetals, and is the second most abundant element in the Earth’s crust, after oxygen.
How many electrons does silicon have?
2, 8, 4Silicon / Electrons per shell
What element has 14 neutrons and protons?
For most of the remaining elements, there are more neutrons than protons, because extra neutrons are needed to keep the nucleus together by overcoming the mutual repulsion of the increasing numbers of protons concentrated in a very small space. For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28.
Which element has the most protons in Group 14?
What element has 47 protons in its nucleus? c.Because most elements consist of a mixture of isotopes and so it is an average. Carbon Family (Group 14)
