Elements and Compounds

105.0K
Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

Periodic Classification of the Elements

59.2K
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

Key Elements for Plant Nutrition

24.3K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond. Elements are classified as atomic or molecular based on the nature of their basic units.
Compounds are pure substances composed of two or more elements in fixed, definite proportions. Compounds are classified as ionic or molecular (covalent) based on the bonds...

Elements: Chemical Symbols and Isotopes02:31

Elements: Chemical Symbols and Isotopes

126.4K
A chemical symbol is an abbreviation used to indicate an element or an atom of an element. For example, the symbol for mercury is Hg. The same symbol is used to indicate one atom of mercury (microscopic domain) or to label a container of many atoms of the element mercury (macroscopic domain).
Some symbols are derived from the common English name of the element; others are abbreviations of the name in another language — Latin, Greek or German. For example, the symbol for aluminum (common name)...

Area of Science:

  • Gerontology
  • Environmental Psychology
  • Architectural Design

Background:

  • Embedded retirement facilities (ERFs) integrate resources and services within communities.
  • Inner corridors in ERFs are primary circulation spaces but often lack stimulating design.
  • Monotonous and enclosed corridor designs can negatively impact older adults' social interaction and psychological well-being.

Purpose of the Study:

  • To analyze spatial tension and behavioral accommodation in ERF inner corridor nodes.
  • To identify design elements influencing older adults' spatial experience and environmental perception.
  • To develop a workflow for extracting and prioritizing spatial design elements using eye-tracking technology.

Main Methods:

  • Systematic identification and analysis of typical inner corridor spatial configurations in ERFs.
  • Integration of eye-tracking technology with subjective assessment methods.
  • Quantitative examination of correlations between eye movement indices and subjective satisfaction.

Main Results:

  • Key spatial design elements influencing visual attention and satisfaction were extracted across spatial interface, atmosphere, and facilities.
  • Correlations between older adults' eye movement patterns and their subjective satisfaction were quantitatively analyzed.
  • Prioritization of critical spatial design elements for enhancing corridor environments was achieved.

Conclusions:

  • The study provides an evidence-based foundation for improving the spatial experience in ERF inner corridors.
  • A generalized workflow for extracting spatial design elements using eye-tracking technology was proposed.
  • Practical guidance is offered for architects and designers to create more engaging and comfortable circulation spaces for older adults.
