What is the general trend of the melting points of elements on the periodic table?
The general trend of melting points of elements on the periodic table increases from left to right across a period and decreases down a group.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
Is melting point a periodic property?
A melting point is a periodic property. Melting point is basically the amount of energy required to break chemical bonds. The more energy required, the stronger the bonds and the higher the melting point. For example, Since Ionic bonds have a transfer of electrons, it requires a lot of energy to break the bonds and has a higher melting point.
What happens to the properties of elements across any periodic of the table?
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
What happens to conductivity when moving across periodic table?
metal--> nonmetal --> metalloid
What happens to the periodic properties as you move across a period?
the mass increases, protons and electrons increase as well
What do you notice about the melting point as you move from left to right across a periodic table?
It starts low on the left, rises dramatically towards the middle and falls again on the right.
What happens to the state of matters you go across the periodic table?
Across the period (left to right), the elements tend to change from solids (metals) to gases (non metals).
Name two elements that are side by side on the periodic table that do not reflect the general trend in melting points for the periods?
One example of two elements that are side by side but do not follow the general melting point trend for the period are sodium (Na) and magnesium (Mg). Sodium has a lower melting point than magnesium, even though it is located to the left of magnesium on the periodic table.
What happens to the atomic number as you go from left to right across the periodic table and why does this happen?
The atomic number increases from left to right across the periodic table because the number of protons in the nucleus of an atom increases. This results in a higher positive charge, leading to a stronger attraction to electrons and a closer binding of electrons to the nucleus.
Does the melting point of a substance is below the room temperature?
Question does not make sense. please re-phrase so we can understand what you are trying to get across. Thanks!
