Why does the general electronegativity trend increases across the same period?
The general electronegativity trend increases across the same period due to the increasing effective nuclear charge, which attracts the electrons more strongly towards the nucleus. As you move from left to right across a period, the number of protons in the nucleus increases while the shielding effect remains relatively constant, resulting in a greater attraction for electrons and higher electronegativity values.
What general statement can summarize the trend in the ionization energy when moving across a period of element?
The ionization energy generally increases across a period from left to right. This is because as you move across a period, the effective nuclear charge increases, making it more difficult to remove an electron. Additionally, the increasing number of protons in the nucleus leads to stronger attraction between the nucleus and the electrons.
Looking at the line plots on your graph describe how boiling point and melting point vary with respect to atomic number?
In general, the boiling and melting points of elements tend to increase with atomic number within a group on the periodic table due to increasing atomic mass and stronger van der Waals forces. However, across a period, these trends can vary; for instance, melting and boiling points may rise to a peak in the middle of the period and then decrease. This is influenced by changes in atomic structure, such as the type of bonding present and electron configuration. Overall, while there is a trend, exceptions do exist based on the specific properties of the elements involved.
In general howe dose atomic radius change across a period from letf to right?
Atomic radius generally decreases across a period from left to right. This is due to the increasing nuclear charge pulling the electrons closer to the nucleus, making the atomic size smaller.
Why does atomic size increase from left to right across a period?
atomic size decreases across a period
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 are thermodynamic properties of covalent hydrides?
hydrogen bonding exists in compounds having partially positively charged hydrogen and highly electronegative atoms bearing partial -ve charge. such intermolecular forces of attraction infleuence the physical properties like melting and boilingg points. the greater the size of atoms the greater the polarazability hence the greater the boiling points for example: the hydrides of fourth period show greater boiling point than those of third period due to ggreater size and greater polarizability.
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 is the general trend in ionization energy?
increases from left to right across a period.
What general trend in electronegativity do you note going down a group across a period?
going down a group, electronegativity decreases going across a period, electronegativity increases
What is the general trend in first ionization energy?
increases from left to right across a period.
What is a melting phase?
The melting phase is a period in time where an object is melting but not completely melted.
Why does the general electronegativity trend increases across the same period?
The general electronegativity trend increases across the same period due to the increasing effective nuclear charge, which attracts the electrons more strongly towards the nucleus. As you move from left to right across a period, the number of protons in the nucleus increases while the shielding effect remains relatively constant, resulting in a greater attraction for electrons and higher electronegativity values.
Which element of Period 4 has the highest melting point?
Tungsten, which has the atomic number 74 and is located in Period 6, has the highest melting point of all the elements in Period 4.
How does metallic of the elements vary across a period?
Across a period, the metallic character decreases.
