How does a molecule of an element differ from a molecule of a compound?
The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. But in a molecule of oxygen (an element), both of the atoms are oxygen.
Does a molecule have to be the same element?
A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
What is the relationship between elements compounds and molecules?
A molecule describes two or more atoms bonded together (all compounds are molecules and some elements are too). The atoms of some elements, like Neon, do not join together and instead exist on their own as individual atoms (they are not molecules).
What is the importance of line in art?
One of the most fundamental elements of art is the line. An important feature of a line is that it indicates the edge of a two-dimensional (flat) shape or a three-dimensional form. A shape can be indicated by means of an outline and a three-dimensional form can be indicated by contour lines.
What are the elements of line?
Types of Lines
- Vertical lines: are straight up and down and perpendicular to horizontal lines.
- Horizontal lines: are straight up and down and perpendicular to vertical lines.
- Diagonal lines: are lines that straight in any direction except vertical or horizontal.
What is the meaning of line in art?
Line is an element of art defined by a point moving in space. It is probably the most fundamental of the elements of design as it is usually the starting place for much of artistic creation. Lines can be vertical, horizontal, diagonal, or curved. They can be any width or texture.
What are the two types of shapes?
There are two main types of shapes, geometric and organic.
What are the six types of lines?
There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc. and are often very expressive.
How do you describe lines?
Lines can be horizontal, vertical or diagonal, straight, curved or free-form. They can be thick or thin, light or dark. Sometimes one line can be all of those things. Lines can be described in many ways — dashed, dotted, rough, smooth, zig-zag, implied.
How important are shapes and lines?
Answer: The main purpose to use line, shape, and form is to define the subject matter and provide the needed information in the painting. Artists learn to visually organize those elements in ways that create strong compositions.
How important is line to this work?
Line is one of the most important Elements of Art. Imagine creating a painting, sculpture or design without drawing lines to divide the paper or canvas into shapes and forms!. Lines can communicate an idea or express a feeling.
What can you say about the color line and shape?
A shape is a two-dimensional design encased by lines to signify its height and width structure, and can have different values of color used within it to make it appear three dimensional. Color is an element consisting of hues, of which there are three properties: hue, chroma or intensity, and value.
What is the difference between a shape and a form?
In the visual arts, shape is a flat, enclosed area of an artwork created through lines, textures, colours or an area enclosed by other shapes such as triangles, circles, and squares. Likewise, a form can refer to a three-dimensional composition or object within a three-dimensional composition.
How is a shape formed?
At its most basic, a shape is created when a line is enclosed: a line forms the boundary, and the shape is the form circumscribed by that boundary. Three lines are used to create a triangle while four lines can make a square. Shapes can also be defined by the artist using value, color, or texture to differentiate them.
What is an example of shape?
The definition of a shape is a specific form, a particular condition, the outline of something you can see even when you cannot clearly make out what it is, or to a something cut out of paper. An example of a shape is a square diamond. An example of shape is a circle cut out of construction paper.
How do you describe a shape?
The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. A graph with a single peak is called unimodal. A single peak over the center is called bell-shaped. And, a graph with two peaks is called bimodal.
