What is Group 3 called in the periodic table?

Transition Metals The elements from Group 3 to 12 are called Transition Metals. They include the Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, and Zinc families of elements. Transition Metals are hard and dense, are good conductors of heat and electricity, and can be bent easily.

What is the atomic number 3?

What group would an element with a 3+ charge be in?

The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges.

Why is lithium's atomic number 3?

A lithium atom contains 3 protons in its nucleus irrespective of the number of neutrons or electrons. ... Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3.

Which Period 3 element has the highest melting point?

Silicon Silicon has strong covalent bonds linking the atoms together in a tetrahedral macromolecular structure. This is a giant covalent structure. Lots of energy is required to overcome the strong covalent bonds, so silicon has the highest melting point.

Why does the third period have 8 elements?

According to the 2n2 rule, the maximum number of electrons in the third period = 2 x (3)2 = 18. But, the last shell cannot accommodate more than 8 electrons so, the number of electrons in third period is 8. Hence, the number of elements is also 8.

Why lithium has most negative E value?

It may be noted that lithium has the most negative Eθ value (table 9.1). ... This behaviour of lithium is attributed to its small size and very high hydration energy. Other metals of the group react explosively with water.

What element has 3 electrons 3 protons and 3 neutrons?

lithium atom b. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3. The mass number, however, is 6 in the isotope with 3 neutrons, and 7 in the isotope with 4 neutrons.

What happens if you breathe in lithium?

Higher exposures may cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath. ► Exposure to Lithium can cause loss of appetite, nausea, vomiting, diarrhea and abdominal pain.
