What is reference group theory?
Reference group theory is based upon the principle that people take the standards of significant others as a basis for making self-appraisals, comparisons, and moving into various social realms (Hyman & Singer: 3). The theory is often used to describe two major types of relationships between individuals and groups.

What is the difference between silica and silicon?
The main difference between Silica and Silicon is that the Silica is a chemical compound and Silicon is a chemical element with the atomic number of 14. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.
What are the three types of reference groups?
There are three basic types of reference groups: informational, utilitarian, and value- expressive.
Is silicon a metal?
Silicon is neither metal nor non-metal; it’s a metalloid, an element that falls somewhere between the two. They look metallic, but conduct electricity only intermediately well. Silicon is a semiconductor, meaning that it does conduct electricity.
What is a reference group?
A reference group is a group to which an individual or another group is compared, used by sociologists in reference to any group that is used by an individual as a standard for evaluating themselves and their own behavior.
What are the example of in-group?

What is a group family of elements?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
What is the example of reference group?
An example of a reference group is a group of people who have a certain level of affluence. For example, an individual in the U.S. with an annual income of $80,000, may consider himself affluent if he compares himself to those in the middle of the income strata, who earn roughly $32,000 a year.

Is Silicon toxic to humans?
Generally, siloxanes (silicones) are well tolerated by the human organism, and therefore they are an integral part of innovative methods of treatment, health care and nursing. They are commonly regarded as non-toxic to humans and the environment, or toxic to a very small extend.
What Colour is silicon?
Pure silicon is a hard, dark gray solid with a metallic lustre and with a octahedral crystalline structure the same as that of the diamond form of carbon, to which silicon shows many chemical and physical similarities.
What are the 9 groups of the periodic table?

- Alkali Metals: Group 1 (IA) – 1 valence electron.
- Alkaline Earth Metals: Group 2 (IIA) – 2 valence electrons.
- Transition Metals: Groups 3-12 – d and f block metals have 2 valence electrons.
- Boron Group or Earth Metals: Group 13 (IIIA) – 3 valence electrons.
What are the 7 groups of the periodic table?
Periodic Table Groups. The Elements displayed in each Periodic Table Group are either Gas, Liquid or Solid at room temperature and are classified in groups as: Alkali Metals, Alkaline Earth Metals, Transition Metals, Metalloids, Other Metals, Non-metals, Halogens, Noble Gases and Rare Earth Elements.
What is the group reference theory explain with example?
Social comparison theory is centered on the belief that there is a drive within individuals to gain accurate self-evaluations. Individuals evaluate their own opinions and define the self by comparing themselves to others. One important concept in this theory is the reference group.

What is a group or family?
The terms element family and element group are used to describe sets of elements sharing common properties. Both describe elements that share common properties, usually based on the number of valence electrons. Usually, either family or group refers to one or more columns of the periodic table.
What’s the difference between silicone and silicon?
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.
