(ii) XY 2 would have high melting and boiling point. Question 72: An element ‘A’ has two electrons in the outermost shell of its atom and coines with an element ‘B’ having seven electrons in the outermost shell, forming the compound AB 2 .
2020/8/4· This page explores the trends in some atomic and physical properties of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium. You will find separate sections below covering the trends in atomic radius, first ionisation energy, electronegativity and physical properties. Even if
Thus, NaCl, in which the ions have charges of 1+ and 1-, has a melting point of 801 C, whereas MgO, in which the charges are 2+ and 2-, melts at 2852 C. The structures of simple ionic solids can be classified as a few basic types.
Melting Point: 1412 degrees C Dysprosium is a meer of the rare earth series of metallic elements. The metal has a bright silver lustre and is relatively hard compared to the others in the series with a high melting point. It is relatively stable in air at room
Why does melting point decrease down the group? Sea of delocalised electrons is further from nucleus, so metallic bonds are weaker Which element in group 2 is anomalous in its melting point? Magnesium Does magnesium have an unusually high or low Low

Most non-metals have low melting points are not in the solid state at room temperature. Some elements have properties that are not typical. For example: Mercury (a metal) has a low melting point
Rationalize why chalk (calcium carbonate) has a higher melting point than motor oil (large compound made from carbon and hydrogen), which has a higher melting point than water and engages in relatively strong hydrogen bonding interactions.
Calcium phosphide (CP) is the inorganic compound with the formula Ca3P2. It is one of several phosphides of calcium, being described as the salt-like material composed of Ca2+ and P3−. Other, more exotic calcium phosphides have the formula CaP, CaP3, Ca2P2, and Ca5P8. Ca3P2 has the appearance of red-brown crystalline powder or grey lumps

The melting point of Si is the highest in Period 3 elements but do take note this doesn''t mean all giant molecules have higher melting points than all metals. In Chemical Bonding we treat metallic bond, ionic bond and covalent bond as strong bonds hence melting points of metals, ionic compounds and giant molecules are all considered high.
