3. Ions and Isotopes (W6L2)

Ions

Ions are Incredible!

Ions are essential for life: if
there were no ions, your body
would not function! The cells
in your body use ions to
communicate.

Ions are also what make up crystals in the Earth's crust,
and lightning in the atmosphere.

From the text, write a sentence drawing out the key meaning to answer;

Why are ions incredible?
Ions are essential for life: if there were no ions, your body would not function! The cells in your body use ions to communicate.

Metinden çıkartılan temel anlamı yanıtlamak için bir cümle yazın;

İyonlar neden olağanüstüdür? İyonlar hayat için önemlidir: Eğer iyonlar olmasaydı, vücudunuz çalışmazdı! Vücudunuzdaki hücreler, iletişim kurmak için iyonları kullanır. İyonlar aynı zamanda Dünya'nın kabuğunu oluşturan kristalleri ve atmosferdeki yıldırımları meydana getiren unsurlardır.

Neutral Atoms

Atoms are electrically neutral particles because they have equal numbers of
positively charged protons and negatively charged electrons.

The positive and negative charges cancel out so the atom has no overall charge.

Multiple Choice

If a neutral atom gains one electron, what charge will it have?
Eğer nötr bir atom bir elektron kazanırsa, hangi yükü olacak?

• Positive/Pozitif
  (cation/katyon)

• Negative/Negatif
  (Anion/anyon)

• Neutral/ nötr

Multiple Choice

If a neutral atom loses one electron, what charge will it have?
Eğer nötr bir atom bir elektron kaybederse, hangi yükü olacak?

• Positive
  (Cation)

• Negative
  (Anion)

• Neutral

Ions Defined

Ions are charged particles that form when an atom or molecule loses or gains
electrons.

Atoms are most stable when their valence (outer) electron shell is full of
electrons. Atoms without full valence shells can gain or lose electrons to
become stable, and in the process they become ions.

Number of protons and electrons are different

Ions are electrically charged particles because they no longer have equal numbers of
positively charged protons and negatively charged electrons.

The positive and negative charges do not cancel out so the ion has an overall charge. This
overall charge is either positive or negative depending on whether the atom loses or gains
electrons.

Open Ended

Why do atoms want exist as ions?
Neden atomlar iyon olarak var olmak ister?

Charges

Electrons are negatively
charged.

If an atom gains electrons, it
becomes a negatively
charged ion.

If an atom loses electrons, it
becomes a positively
charged ion.

Types of Ions

The group (column) on the periodic table the element is in says how

many electrons are gained or lost. The diagram shows how many
electrons are gained or lost for the columns on the Periodic table.

Draw

Colour in the metals on the periodic table.

Types of Ions

An atom that is negatively
charged is an ANION
•Non-metals gain to fill outer shell
•Has more electrons than protons
•Gains electrons from other atoms

An atom that is positively charged
is a CATION
•Metals lose to empty outer shell
•Has less electrons than protons
•Loses electrons and gives them to
other atoms
