How does phosphorus bond with oxygen?
Since oxygen is more electronegative when compared to bromine it creates a larger positive charge on the phosphorus and a larger negative charge on the oxygen. The oxygen then sends its lone pairs into the empty d orbitals of phosphorus creating a pi bond which is stable.
Is germanium positive or negative?
All the carbon group atoms, having four valence electrons, form covalent bonds with nonmetal atoms; carbon and silicon cannot lose or gain electrons to form free ions, whereas germanium, tin, and lead do form metallic ions but only with two positive charges.

Which electrons have the most energy?
What Are Energy Levels?Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. … Q: In the atomic model Figure above, where would you find electrons that have the most energy?A: Electrons with the most energy would be found in energy level IV.More items…•
What is the bonding power of germanium?
The bond energy in the gaseous diatomic species GeGe is 263.6 ±7.1 kJ mol-1.
What are 3 uses for germanium?
The largest use of germanium is in the semiconductor industry. When doped with small amounts of arsenic, gallium, indium, antimony or phosphorus, germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps.
What does germanium do for the body?
There have been claims that germanium may be beneficial for health, including improving the immune system, oxygen supply in the body, and destroying free radicals. According to Healthline, germanium has also been considered to be beneficial in treating allergies, asthma, arthritis, HIV/AIDS and various forms of cancer.
Which energy level has the least energy?
At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons.
What element has four energy levels?
BromineWhich element has four energy levels (electron shells)? Bromine is in period (row) 4 on the periodic table. This means it has 4 energy levels.

Is germanium harmful to humans?
Germanium is LIKELY UNSAFE when taken by mouth in elemental form and in the form of certain compounds such as germanium oxide. There have been more than 30 reports of kidney failure and death linked with use of these forms of germanium. It builds up in the body and can damage vital organs such as the kidneys.
Why are energy levels not equally spaced?
Unlike a ladder, which has a limited length, the energy levels of an atom extend infinitely out from the nucleus and the energy levels are not evenly spaced. As the distance from the nucleus increases, the levels get closer together and contain more-energetic electrons (Figure 5.4). … FIGURE 5.4 Energy levels.
Why is Germanium a semiconductor?
Germanium atoms have one more shell than silicon atoms, but what makes for the interesting semiconductor properties is the fact that both have four electrons in the valence shell. As a consequence, both materials readily constitute themselves as crystal lattices. Substituted atoms alter the electrical properties.
Does germanium react with oxygen?
At red heat, germanium reacts with oxygen in air to from germanium dioxide.
Does tin have 4 energy levels?
Tin is located in group 14 of the periodic table, which means that it has 4 electrons in its outermost shell, i.e. 4 valence electrons.
