Nate and Clara are drawing pictures with markers. There are 8 markers in a set. Nate has 9 markers and Clara has 7. What can Nate and Clara do so that each of them has a full set?

Multiple Choice

Click Pause. Elements can be classified as metals and nonmetals. Metals do not hold on to their valence electrons very tightly, while nonmetals hold their electrons tightly. Ionization energy is a measure of how tightly the valence electrons are held. Try pulling an electron away from each atom. Based on this experiment, which atom is a metal?

• sodium
• chlorine

• neither

Get the Gizmo ready: 

• Click Reset.

Check that sodium and chlorine are still selected.

Introduction: Some of the particles that make up atoms have an electrical charge. Electrons are negatively charged, while protons are positively charged. Particles with opposite charges (+ and –) attract, while particles with the same charge (+ and + or – and –) repel.

Like charges do what?

• repel
• attract

Select Lithium (Li) and Oxygen (O). Look at the purple lithium atom and the red oxygen atom. Recall that most atoms are stable when their outermost ring has eight electrons. Some atoms, such as lithium and beryllium, are stable when their outermost ring has two electrons. How many electrons will the lithium atom give up to become stable?​

Select answer

How many more electrons does the oxygen atom need to become stable?​

Can a stable compound be made from just these two atoms? Explain why or why not.

The answer is no. Lithium only has one electron to give and oxygen needs two electrons

Dropdown

Click Add metal to add another lithium atom, and then transfer electrons from each lithium to the oxygen. Click Check. Turn on Show charge. What is the charge of each ion?
