The tendency to lose electron decreases along a period. The tendency to gain electron increases.
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.
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.
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.
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.
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.
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
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.
Groups of the Periodic Table of Elements.
Chemical reactivity first decreases.then it increases as we move across a period.
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.
Electronegativity increases across (left to right) the periodic table and decreases on going down.
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.
They become less reactive.
the no. of electrons increses
Ionisation energy decreases down the group. It is easy to remove an electron.
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.
The statement applies to the horizontal rows or periods in the Periodic Table is that properties change going across each row.
