Crate use_atomic_number 

use-atomic-number

Atomic-number validation and neutral-atom helpers.
Small direct helpers for validating atomic numbers and mapping element names or symbols to proton counts.

Surface

Item	Purpose
is_valid_atomic_number()	Range check for 1 through 118
atomic_number_from_symbol()	Symbol-to-atomic-number lookup
atomic_number_from_name()	Name-to-atomic-number lookup
proton_count()	Proton count for a valid atomic number
electron_count_neutral_atom()	Neutral electron count for a valid atomic number

Example

use use_atomic_number::{atomic_number_from_name, atomic_number_from_symbol, proton_count};

assert_eq!(atomic_number_from_symbol("Na"), Some(11));
assert_eq!(atomic_number_from_name("oxygen"), Some(8));
assert_eq!(proton_count(79), Some(79));

Atomic-number validation and lookup helpers.

Functions

atomic_number_from_name

Looks up an atomic number from an element name using ASCII case-insensitive matching.

atomic_number_from_symbol

Looks up an atomic number from a symbol.

electron_count_neutral_atom

Returns the electron count for a neutral atom with the given atomic number.

is_valid_atomic_number

Returns true when the atomic number is between 1 and 118 inclusive.

proton_count

Returns the proton count for a valid atomic number.
