NAME

Chemistry::PeriodicTable - Provide access to chemical element properties

VERSION

version 0.0501

SYNOPSIS

use Chemistry::PeriodicTable ();

my $pt = Chemistry::PeriodicTable->new;

my $filename = $pt->as_file;

my $headers = $pt->header;
my $symbols = $pt->symbols; # element properties keyed by symbol

$pt->number('H');        # 1
$pt->number('hydrogen'); # 1

$pt->name(1);   # Hydrogen
$pt->name('H'); # Hydrogen

$pt->symbol(1);          # H
$pt->symbol('hydrogen'); # H

$pt->value('H', 'weight');               # 1.00794
$pt->value(118, 'weight');               # 294
$pt->value('hydrogen', 'Atomic Radius'); # 0.79

DESCRIPTION

Chemistry::PeriodicTable provides access to chemical element properties.

ATTRIBUTES

symbols

$symbols = $pt->symbols;

The computed hash-reference of the element properties keyed by symbol.

10 Atomic Radius
11 Electronegativity
12 First Ionization Potential
13 Density
14 Melting Point (K)
15 Boiling Point (K)
16 Isotopes
17 Specific Heat Capacity
18 Electron Configuration
19 Display Row
20 Display Column

METHODS

new

$pt = Chemistry::PeriodicTable->new;

Return the data filename location.

number

$n = $pt->number($symbol);
$n = $pt->number($name);

Return the atomic number of either a symbol or name.

name

$n = $pt->name($number);

Return the atom name of either an atomic number or symbol.

symbol

$s = $pt->symbol($number);
$s = $pt->symbol($name);
