What can they do so that each has a full set? Just like the students described above, nonmetal atoms can share electrons.

Oxygen, Nitrogen & Carbon and Covalent Chemical Bonds

To begin, check that Fluorine is selected from the Select a substance menu. Click Play to see the electrons orbiting the nucleus of each atom. The outermost electrons in each atom are called valence electrons. How many valence electrons does each fluorine atom have? Click Pause. Drag an electron from the left atom to the right atom. Click Play. What happens? Click Pause, drag an electron from the right atom to the left, and then click Play. What happens now. Introduction: The electrons that orbit the nucleus of an atom are arranged into shells.

The first shell contains up to two electrons and the second contains up to eight electrons. Most elements are stable when they have eight valence electrons—a rule of thumb known as the octet rule. Elements with less than five electrons are stable with two valence electrons. Question: What happens when atoms share electrons? Predict : Each hydrogen atom has one valence electron, but it needs two electrons to be stable. How can both hydrogen atoms each achieve a stable configuration?

Form a bond : Drag the electrons so that they move around both hydrogen atoms. Click Play to observe them in orbit, and then click Check. You have created a. Congratulations, you have completed a of hydrogen! Because the molecule has two atoms, it is a. Click the icon to take a snapshot of your completed molecule. Right-click the image, and click Copy Image.Please Enter a Question First.

Maggie is sitting at a table with Fred and Florence. Maggie has 10 markers, but Fred and Florence each have only 7 markers. How can they share markers so each has 8? Just like students sharing markers, atoms sometimes share or swap electrons.

By doing this, atoms form bonds. To begin, check that Sodium Na and Chlorine Cl are selected from the menus at right. Click Play to see electrons orbiting the nucleus of each atom. Note: These atom models are simplified and not meant to be realistic. Each atom consists of a central nucleus and several shells that contain electrons.

The outermost electrons are called valence electrons. Inner electrons are not shown. How many valence electrons does each atom have? 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. Electron affinity 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?See All. See All Free Gizmos.

Critter Count Modeling Multiplication Now that spring is here, all kinds of critters are coming out of hiding! In the Critter Count Gizmo, groups of these critters gather on leaves to model multiplication.

Aimed at younger elementary students, the Gizmo allows students to choose a type of bug, and then group the bugs on leaves. For example, a product like 5 x 2 is shown as 5 leaves with 2 critters on each leaf. Then students can click the Count button to compare the group model to repeated addition. When students click the Array button, the groups of bugs are rearranged into columns and rows.

In the array model, the number of rows is the same as the number of groups leaves and the number of columns is the same as the number of bugs in each group on each leaf.

So, the product 5 x 2 is shown as 5 rows of 2 critters. Go to Gizmo! Gizmo of the Week Critter Count Modeling Multiplication Now that spring is here, all kinds of critters are coming out of hiding! Read More.Flora is missing the red marker, and Frank is missing the blue marker.
