Fundamentals (English)
1. Atomic Number: Protons in an atom. Identifies the element. Equals electrons in neutral atoms.
2. Mass Number: Protons + Neutrons in nucleus.
3. Finding Neutrons: Mass Number − Atomic Number.
4. Symbols: Na (Sodium), H (Hydrogen). 1st: CAPITAL, 2nd: lower.
Fundamentos (Español)
1. Número Atómico: Protones. Identifica al elemento e indica e- neutrales.
2. Número de Masa: Protones + Neutrones.
3. Neutrones: Masa − Número Atómico.
4. Símbolos: Na (Sodio). 1ra: MAYÚSCULA, 2da: minúscula.
5-7. Types: Metals (left, shiny), Nonmetals (right, brittle), Metalloids (zig-zag boundary).
8. Groups: Columns. Similar properties. Same valence e-.
9. Periods: Horizontal rows. Energy levels.
10. Transition: Center block elements (Groups 3-12).
5-7. Tipos: Metales (izq), No Metales (der), Metaloides (línea zigzag).
8. Grupos: Columnas. Mismos e- de valencia.
9. Períodos: Filas. Niveles de energía.
10. Transición: Elementos del centro (Grupos 3-12).
11. Valence e-: Outermost electrons. Determine reactivity.
12. "A" Number: Refers to Mass Number (A=P+N).
13. Isotopes Same element with different numbers of neutrons.
11. Valencia: Electrones externos. Determinan reactividad.
12. Número "A": Refiere al Número de Masa.
Hidden Mismo elemento con diferente número de neutrones.

Quick Reference
• At. # = Protons. | Mass # = Protons + Neutrons.
• Isotopes: Same element, different neutron count.
Referencia Rápida
• N. At. = Protones. | N. Masa = Protones + Neutrones.
• Isótopos: Mismo elemento, diferentes neutrones.

Atom Atlas: Organization & Isotopes
Matching / Emparejamiento
1. Isotopes: B (Same element, diff neutrons)
2. Atomic Number: C (Identifies element)
3. Mass Number: A (Protons + Neutrons)
🔬 Isotope Table / Tabla
Carbon-14: Neutrons = 8, Mass = 14
Oxygen-18: Neutrons = 10, Mass = 18
Salida / Exit Ticket
Q2: Yes, provided their atomic number remains the same (same element).
Q3: 10 Neutrons (18 - 8 = 10).
Q4: Right side of the table (to the right of the zigzag line).
Analysis / Análisis
1. Properties (11P, 12N)?
Atomic Number = 11 (Protons). Mass Number = 23 (11+12).
2. Atom A (6P) vs Atom B (7P)?
No. They cannot be isotopes of each other because isotopes must be the same element (have the same number of protons). Atom A is Carbon, Atom B is Nitrogen.
Comprehension Question (Notes):
They are the same element because they have the same number of protons (atomic number 6), which defines their identity. Their mass is different only because they have different numbers of neutrons.
