What happens to non metals across the periodic table?
Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.
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.
From left to right across the second period of the periodic table?
The second period of the periodic table contains elements from lithium to neon, in increasing atomic number order. These elements have increasing numbers of protons and electrons as you move from left to right across the period, resulting in changes in properties such as atomic size and reactivity.
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 is the horizontal row across the periodic table?
A horizontal row on the periodic table of elements is called a period.
What do you notice about the boiling points as you move from left to right across the periodic table?
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.
What happens to the reactivity of non metals if you move from left to righton the periodic table?
The reactivity of nonmetals generally decreases as you move from left to right across the periodic table. This is because nonmetals on the right side of the periodic table have a higher electronegativity, making them less likely to lose electrons and more likely to gain electrons.
What are semiametals?
As we look across the periodic table from left to right, we see metals on the left, transition metals through the middle and nonmetals on the right. What we left out was that group of elements between the transition metals and the nonmetals, and these semimetals are called metalloids.Metaloids have properties that are in between those of transition metals and nonmetals, or perhaps properties that are some combination of those of transition metals and nonmetals. The elements in this group include boron, silicon, germanium, arsenic, antimony and tellurium.
Why metals more lose electrons more easily than nonmetals?
nonmetals are located in the right side of the Periodic Table. The Ionization energy(the amount of energy used to remove an electron) tends to increase from left to right across a period.It is difficult to remove the electrons from the right side because they are becoming stable
What happens to the metallic character of the element as you go across the periodic table?
The metallic character tends to decrease as you move across the periodic table from left to right. This is because elements on the left side of the periodic table, such as alkali metals and alkaline earth metals, tend to exhibit more metallic properties, while elements on the right side, such as nonmetals, tend to have less metallic character.
How is metallic character shown on the periodic table?
The metallic elements on a periodic table may be represented by a certain color unlike those of other elements. Most periodic tables have elements in different colors, so try looking at the key that shows what each color represents for that element.
A row across the periodic table is called a?
groupsi
A row of elements across the periodic table is an?
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
How do you tell the reactiveness of a non metal on the periodic table?
The periodicity of nonmetals is that reactivity increases from left to right across a period, through group 17, the halogens. As you move down a group, reactivity decreases. Fluorine is the most reactive element.
What happens to non metals across the periodic table?
Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.
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.
Why don't atoms simply get larger you read across the periodic table?
because the no. of shells in the atoms across the Periodic Table remains the same
