What else can I help you with?
What do the elements sulfur S nitrogen N phosphorus P and bromine Br have in common?
If you on the periodic table, all of these elements are on the right side of the zig- zag line that is made up of the metalloids. The elements on the right side of the zig-zag line are all non-metals. So all theses elements are non-metals.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
In a group labeled as A, as atomic numbers increase across a period, the reactivity of elements generally decreases. This is because as you move from left to right across a period, the elements have more protons in the nucleus, which leads to stronger nuclear charge and less tendency to lose electrons and react with other elements.
How do the elements in the period you choose compare?
In a period of the periodic table, elements have the same number of electron shells but different numbers of electrons in their outer shell. As you move across a period from left to right, the number of protons and electrons increases, causing elements to become more electronegative and decrease in atomic radius. Additionally, elements within a period show a trend of increasing metallic to non-metallic properties.
What is the name of halogen in period 3?
If you have a periodic table of the elements available, look at the second column from the right. Those elements are often referred to as "halogens". The "rows" in the periodic table are often referred to as the "periods". So the halogen from the third period would be "CL", or chlorine. Glad to help with your homework.
Why does the change for the atomic radii of elements in period 3 from sodium to argon look similar to period 2?
The atomic radii of elements in period 3 from sodium to argon decrease due to a greater nuclear charge pulling electrons closer to the nucleus. This trend is similar to period 2 because both periods follow the same pattern of increasing nuclear charge as you move across the period, leading to a similar decrease in atomic radii.
What are the period and group trends in electronegativites?
In general, electronegativity tends to increase across a period and decrease down a group on the periodic table. This means that elements on the right side of the periodic table typically have higher electronegativities than elements on the left side. Additionally, elements in the same group tend to have similar electronegativities due to their similar electron configurations.
What is a set of elements that runs from left to right?
period
What are the two elements in the same period as magnesium?
Magnesium is in period 3 of the periodic table. The two elements in the same period as magnesium are aluminum (Al) and silicon (Si). Both elements follow magnesium in this period, with aluminum located to the right of magnesium and silicon further to the right.
How does the electronegativity of elements change across a period?
The electronegativity of elements generally increases across a period from left to right. This means that elements on the right side of the periodic table tend to attract electrons more strongly than elements on the left side.
Are period 1 elements more electronegative than period 2 elements?
No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.
What element in period 3 is metallic?
In period three, all elements but the four on the right are metallic.
How does an element's electronegativity relate to its position on the periodic table?
Electronegativity generally increases as you move from left to right across a period on the periodic table, and decreases as you move down a group. This trend occurs because elements closer to fluorine (the most electronegative element) on the periodic table have higher electronegativities.
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
The row of elements going left to right on the periodic table is called?
This row of chemical elements is a "period".
How can you tell if an element is more metallic than another?
the more metallic element will be the one below in group # or the one closer to the left in the period( the more metallic will be the one closer to the bottom left corner) since they have the lowest ionization energy and lower electronegativity
What is the term for a row of elements going from left to right on the periodic table?
Period
What is the left to right rows on the period table called?
The left to right rows on the periodic table are called periods. Each period represents the energy levels of the elements, with the elements in the same period having the same number of electron shells.
