It will sink below the surface. Since dish soap is a surfactant, it will alter the water's surface tension. Lowering the surface tension, the water will no longer be able to support the mass of the twig.

7. Interpret Data A company plans to make an electronic device. They need to use an element that has chemical behavior similar t
Goryan [66]

Germanium (Ge) is an element that has chemical behavior similar to that of silicon (Si) and lead (Pb). As it has an atomic mass greater than that of sulfur (S), but less than that of cadmium (Cd).

<h3>Why does the element of the same group have similar chemical behavior?</h3>

The chemical behavior of elements depends on the number of valence electrons in their outermost shell. Elements placed in the same group have the same number of valence electrons. Therefore, elements placed in the same group of the periodic table have similar chemical properties.

The elements having a similar outer electronic configuration in their atoms are arranged in the same group of the periodic table. These valence electrons are responsible chemical properties and reactivities of the elements.

Therefore, silicon and lead can be replaced by any element belonging to the same group in which Si and Pb are present. So we have germanium and tin. But germanium is the element that has an atomic mass greater than sulfur (S), but less than cadmium (Cd).
