How do you construct an n type semiconductor?
An n-type semiconductor is formed by doping a pure semiconductor (silicon or germanium, for example) with atoms of a Group V element, typically phosphorus or arsenic. The dopant may be introduced when the crystal is formed or later, by diffusion or ion implantation.
What is the charge for a group six ion?
The most common charge (or valency) is -2. But there are compounds formed by elements of group VIA with valency from -2 to +6
What is the usual charge on an ion from group 7A?
The usual charge on an ion from group 7A (also known as group 17) is -1. This is because elements in group 7A, such as fluorine, chlorine, and bromine, typically gain one electron to achieve a full outer electron shell, resulting in a -1 charge.
What type of ion is formed when an atom loses an ion?
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
What type of ion will the element in period 4 group 5 form on the periodic table?
The element in period 4 group 5 (also known as Group 15) will typically form an ion with a 3- charge, known as a nitride ion. This is because elements in this group tend to gain three electrons to achieve a stable electron configuration.
What ion element carry the 3- charge?
Everything in Group 5 except bismuth e.g. nitrogen, phosphorus, arsenic, and occasionally antimony
What type of ion is formed from a neutral atom when it gains electrons?
Negatively charged anions are formed.
Which group have two valence electrons and make a 2 ion?
alkaline earth metals or group 2 elements have two valence electrons and make +2 ion.
What group is chloride in?
The chloride ion is formed when the element chlorine picks up one electron to form an anion (negatively-charged ion) Cl−Chlorine is in the halogen group (a halide)
What type of bond is formed when a element makes a salt?
ion attraction
Which group on the periodic table loses 2 electrons to create an ion?
The elements in group 2 lose 2 electrons to create an ion.
What family is bromide in?
Bromide is in the halogen family, which is Group 17 (Group VIIA) on the periodic table. Members of this family include elements like fluorine, chlorine, iodine, and astatine. Bromide is a negatively charged ion formed when bromine gains an electron.
