Q2 ION FORMATION

How does an atom become a charged ion?

• gaining or losing protons

• gaining or losing electrons

• gaining or losing neutrons

• by electrical shock

What is an ion?

• An atom with a neutral charge.

• An atom that has lost or gained protons.

• An atom that carries either a positive or negative charge.

• An atom that only carries a positive charge.

How many valence electrons does an element in Group IVA typically possess?

• 1

• 2

• 4

• 8

Which statement accurately describes non-metals in terms of electron behavior?

• They tend to lose electrons and become positively charged.

• They tend to gain electrons and become negatively charged.

• They have low electronegativity values.

• They are typically found on the leftmost side of the periodic table.

What is ionization energy?

• The energy released when an atom accepts an electron.

• The ability of an atom to attract electrons.

• The energy required to remove electrons from an atom.

• The energy stored within an atom's nucleus.

How does an element get a positive charge?

• Gain protons

• Lose protons

• Gain electrons

• Lose electrons

When do we call an atom an ion?

• hen it has an imbalance between protons and electrons

• When it has more neutrons than protons

• When it has more protons than neutrons

• When it has an equal number of protons and electrons

  
  

Why do atoms form ions according to the octet rule?

• To become larger

• To have empty valence shells

• To achieve a full outer electron shell

• To conduct electricity

Sodium (Na) has 1 valence electron. According to the octet rule, what will sodium most likely do when forming a bond?

• Gain 7 electrons

• Lose 1 electron

• Share 1 electron

• Lose 7 electron

An atom tends to gain, lose, or share electrons to have eight electrons in its valence shell. This statement describes:

• Ionic bonding

• Covalent bonding

• Octet rule

• Electronegativity
