— read-onlyThe available properties (including floating-point properties) of the chemical elements. For details, see the description
attribute of each property.
A property of the chemical elements. Property instances are accessible through the properties
lists of categories, or as module-level attributes (see above).
unicode name
— read-onlyThe translated name of the property.
bool has_format
— read-onlyWhether a compose-style format for values is defined.
unicode format
— read-onlyA translated compose-style format for values of the property. If the format is undefined, an empty string.
unicode description
— read-onlyA translated explanatory description of the property.
list(Message) sources
— read-onlyCitations for the sources of values for the property, as Message
s.
bool is_colorable
— read-onlyWhether values of the property have color representations.
null make_entry (EntriesView view, unicode|value_base value)
Possibly adds a value for this property to an EntriesView
. If value
is unicode, an entry will always be made. If value
is a value_base
subclass, an entry will be made only if value
is defined or belongs to an always-output class.
view | The EntriesView to be populated. |
value | The value to be added. |
A floating-point property of the chemical elements. Inherits from Property
.
bool is_scale_valid
— read-onlyWhether the scale of values for this property is valid. The scale is valid if one or more elements has a defined value for this property and those values are not all equal.
float get_scale_position (Float instance[, bool logarithmic=False])
Returns the position on a normalized 0.0 to 1.0 scale for an instance of this property. Raises ValueError
if the property does not have a valid scale, or if instance
is not a defined value.
instance | A defined Float value for this property. |
logarithmic | Whether to compute the position on a logarithmic instead of linear scale. |
float minimum
— read-onlyThe least value of this property for any element. Raises ValueError
if the property does not have a valid scale.
float linear_medium
— read-onlyThe value of this property that has a position of 0.5 on a linear scale. Raises ValueError
if the property does not have a valid scale.
float logarithmic_medium
— read-onlyThe value of this property that has a position of 0.5 on a logarithmic scale. Raises ValueError
if the property does not have a valid scale.
float maximum
— read-onlyThe greatest value of this property for any element. Raises ValueError
if the property does not have a valid scale.
A category of properties of the chemical elements. Categories instances are accessible through the categories
list, or as module-level attributes (see above).
unicode name
— read-onlyThe translated name of the category.
list(Property) properties
— read-onlyThe properties in the category.
null make_header (EntriesView view)
Adds the category name to an EntriesView.
