How does ionic radius change as you move down and across the periodic table?
As you move down a group in the periodic table, the ionic radius tends to increase due to the addition of new electron shells. Across a period from left to right, the ionic radius generally decreases as the increasing nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller radius.
What are the periods on the periodic table and how do they relate to the organization of elements?
The periods on the periodic table are the horizontal rows that indicate the number of electron shells in an atom. Each period represents a different energy level for the electrons. The organization of elements in periods helps to show how the properties of elements change as you move across the table from left to right.
What define period of the periodic table?
The period of the periodic table refers to the horizontal rows in the table, which indicate the number of electron shells an element's atoms have. As you move across a period, the number of protons and electrons increases by one, leading to a gradual change in properties.
In terms of the periodic table is there a gradual or abrupt change when it comes to covalent bonds?
There is a gradual change in the nature of covalent bonds as you move across a period on the periodic table. Covalent bonds become more polar and less covalent as you move from left to right across a period due to increasing electronegativity of the elements.
How is the electron configuration of an atom related to its tendency to give up or gain electrons during a chemical change Show at least 2 examples or illustrations.?
The electron configuration of an atom determines the number of valence electrons, which are involved in chemical reactions. Atoms with few valence electrons tend to lose electrons to achieve a stable configuration, like group 1 elements (e.g., sodium). Conversely, atoms with nearly full valence shells tend to gain electrons to attain stability, as seen in group 7 elements (e.g., fluorine). This interaction between electron configuration and valence electron number dictates an atom's tendency to give up or gain electrons during a chemical change.
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 information do you get from periodic table periods?
Periods in the periodic table represent the number of electron shells an element's atoms have. As you move across a period from left to right, the number of protons increases by one, resulting in a gradual change in chemical properties. Elements in the same period generally have similar outer electron configurations.
Properties of elements change according to a pattern across the?
Groups of the Periodic Table of Elements.
How does chemical reactivity change as you move across the periodic table?
Chemical reactivity first decreases.then it increases as we move across a period.
How does ionic radius change as you move down and across the periodic table?
As you move down a group in the periodic table, the ionic radius tends to increase due to the addition of new electron shells. Across a period from left to right, the ionic radius generally decreases as the increasing nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller radius.
How does electronegative change going down and across the table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
What are the periods on the periodic table and how do they relate to the organization of elements?
The periods on the periodic table are the horizontal rows that indicate the number of electron shells in an atom. Each period represents a different energy level for the electrons. The organization of elements in periods helps to show how the properties of elements change as you move across the table from left to right.
How do the properties of each family of metals change as you move across the periodic table?
They become less reactive.
How does the number of valence electrons change as you go across the 2nd period of the periodic table?
the no. of electrons increses
How does the ionisation energy change down the groups in the periodic table?
Ionisation energy decreases down the group. It is easy to remove an electron.
What define period of the periodic table?
The period of the periodic table refers to the horizontal rows in the table, which indicate the number of electron shells an element's atoms have. As you move across a period, the number of protons and electrons increases by one, leading to a gradual change in properties.
What statement applies to the horizontal rows or periods in the periodic table.?
The statement applies to the horizontal rows or periods in the Periodic Table is that properties change going across each row.
