As atomic number increases, the number of electrons also increases except for Period 1 because it ends with a number of valence electrons with higher energy , (This pattern means that the elements within a group always have the same number of valence electrons having the result of having similar properties.)
What else can I help you with?
Do element properties change as you move across a period or whithin a group?
Yes, element properties change as you move across a period due to the increasing number of protons in the nucleus and the change in electron configuration. Within a group, elements have similar properties because they have the same number of valence electrons, which determine their reactivity.
What is the difference between a chemical change and physical change?
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
Why do the properties of elements of change in a regular way across a period?
Because certain groups have different characteristics, so when you move to a different group the characteristics will be different.
Why do properties of element change in Regular way across a period?
As atomic number increases, the number of electrons also increases except for Period 1 because it ends with a number of valence electrons with higher energy , (This pattern means that the elements within a group always have the same number of valence electrons having the result of having similar properties.)
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.
How do the physical and chemical properties properties of the elements change?
periodically within a group
What does the periodic law say about the properties of element?
They change with atomic number.
Why is being flammable a chemical property rather than a physical property?
Physical properties of an element are those in which there is no change in its state. For example, the color and density of an element are physical properties. If an element is flammable, it goes through a reaction and burns, and there is a change in state. When there is a reaction that results in a change of state, Flammability is a chemical property.
When the repeating chemical and physical properties of element change periodically with the element atomic number it is called the?
the periodic law i think
Properties of elements change according to a pattern across the?
Groups of the Periodic Table of Elements.
Do atoms have the same properties as an element?
No, atoms are the smallest units of matter that retain the properties of an element. The properties of an element are determined by the number of protons in its nucleus, which defines its atomic number and unique characteristics. When atoms combine to form molecules, the properties may change due to new interactions.
What element is ferromagnetic and when combined with silver its magnetic properties change?
Iron is ferromagnetic and when combined with silver, the resulting alloy loses its ferromagnetic properties.
