Understanding Silver Atoms and Ions

This video tutorial explains how to determine the number of protons and electrons in the silver ion (Ag+). It begins by identifying silver's atomic number on the periodic table, which is 47, indicating 47 protons. The video then explains that in a neutral silver atom, there are also 47 electrons. However, in the silver ion (Ag+), one electron is lost, resulting in 46 electrons and a positive charge. The tutorial emphasizes the concept of ion formation, where losing an electron results in a positive ion, while gaining an electron results in a negative ion. Additional resources for finding the number of neutrons in silver isotopes are provided.

What is the atomic number of silver?

• 46

• 49

• 47

• 48

How many protons does a silver atom have?

• 46

• 47

• 45

• 48

What is the significance of the atomic number in determining the number of protons?

• It equals the number of neutrons

• It equals the number of electrons in ions

• It is unrelated to protons

• It equals the number of protons

In a neutral silver atom, how do the number of protons and electrons compare?

• More electrons than protons

• More protons than electrons

• Cannot be determined

• Equal number of protons and electrons

What is the relationship between protons and electrons in a neutral atom?

• Protons are double the electrons

• Electrons are double the protons

• They are equal

• Protons are half the electrons

What happens to the charge of a silver atom when it loses an electron?

• It becomes a neutron

• It remains neutral

• It becomes positively charged

• It becomes negatively charged

How many electrons does a silver ion (Ag+) have?

• 48

• 46

• 45

• 47

What is the charge of a silver ion after losing one electron?

• Negative

• Positive

• Neutral

• Double positive

Why does losing an electron result in a positive charge?

• Because the atomic number changes

• Because neutrons are removed

• Because electrons are negative

• Because protons are added

Where can you find more information about the number of neutrons in silver isotopes?

• In the periodic table
