Ions Practice

A positive ion is called an

• Anion

• Cation

Answer explanation

A positive ion is called a cation. Cations are formed when an atom loses one or more electrons, resulting in a net positive charge. In contrast, anions are negative ions formed by gaining electrons.

A negative ion is called an

• Anion

• Cation

Answer explanation

A negative ion is called an anion. This occurs when an atom gains one or more electrons, resulting in a net negative charge. In contrast, a cation is a positively charged ion.

If Chlorine (Cl) gains an electron what is its charge?

• +1

• -1

• +2

• -2

Answer explanation

When Chlorine (Cl) gains an electron, it becomes negatively charged. This is because gaining an electron adds a negative charge, resulting in a charge of -1. Therefore, the correct answer is -1.

If Potassium lost an electron what is its charge?

• -1

• +2

• -2

• +1

Answer explanation

When potassium (K) loses one electron, it has one less negative charge than protons, resulting in a +1 charge. Therefore, the correct answer is +1.

If Iron LOST two electrons what is its charge?

• -2

• +1

• -1

• +2

Answer explanation

When iron loses two electrons, it has a deficiency of two negatively charged particles, resulting in a net positive charge. Therefore, the charge of iron after losing two electrons is +2.

What is the charge of an Ion that has 12 protons and 13 electrons

• -2

• +2

• -1

• +1

Answer explanation

An ion's charge is determined by the difference between protons and electrons. Here, 12 protons (+12) and 13 electrons (-13) result in a charge of +12 - 13 = -1. Thus, the correct answer is -1.

What is the charge of an Ion that has 56 protons and 55 electrons?

• -1

• +1

• +2

• -2

Answer explanation

An ion's charge is determined by the difference between protons and electrons. Here, 56 protons and 55 electrons result in a charge of +1 (56 - 55 = +1). Therefore, the correct answer is +1.

What is the charge of an Ion that has 46 protons and 48 electrons

• -1

• +2

• +1

• -2

Answer explanation

An ion's charge is determined by the difference between protons and electrons. Here, 46 protons (+46) and 48 electrons (-48) result in a charge of +46 - 48 = -2. Thus, the correct charge is -2.

What is the charge of an Ion that has 5 protons and 3 electrons

• +2

• -1

• +1

• -2

Answer explanation

An ion's charge is determined by the difference between protons and electrons. Here, 5 protons (+5) and 3 electrons (-3) result in a charge of +2. Therefore, the correct answer is +2.

If Copper LOST an electron what is its charge?

• -1

• -2

• +1

• +2

Answer explanation

When Copper loses an electron, it has one less negative charge, resulting in a net positive charge. Therefore, the charge of Copper after losing an electron is +1.
