de un átomo del mismo elemento?

What is one way an ion differs from an atom of the same element?¿Cuál es un forma en que un ion difiere de un

átomo del mismo elemento?

What is one thing an atom, an isotope and an ion of the same element have in common?¿Qué es una cosa que un átomo, un isótopo y un

Vocabulary: IsotopeVocabulario: Isótopo

An atom of an element with a different number of neutrons. All isotopes have different atomic masses.

Un átomo de un elemento con un número diferente de neutrones. Todos los isótopos tienen diferentes masas atómicas.

Guided Practice

The ___________ identifies an isotope

El ___________ identifica un isótopo

Mass number!

número másico

MASS NUMBER = # OF PROTONS + # OF NEUTRONS

Número másico = # DE PROTONES + # DE NEUTRONES
