How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How can valency change across a period?
Valency, or the combining capacity of an element, can change across a period due to variations in the number of valence electrons. As you move from left to right across a period in the periodic table, elements typically gain more valence electrons, transitioning from metals to non-metals. This change influences their ability to form bonds, with metals often having low valency and non-metals having higher valency. Consequently, the types of chemical bonds and compounds that elements can form also vary across the period.
What are two ways in which atoms of different elements are different from one another?
The number of protons, which determines the element's identity, varies between atoms of different elements. The arrangement of electrons in an atom, specifically the number of electrons in the outermost shell, differs among elements.
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 does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
Why do numbers of electrons change across a period of elements?
Why not?If two atoms have the same number of protons, they're the same element. Therefore, unless they're electrically charged, they must have the same number of electrons as well. So the number of electrons in two different elements must be different if the atoms are electrically neutral.
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.
What happens to valence electrons as you move across the row?
The number of valence electrons remains the same as you move across a row on the periodic table. For example, in row 2 (elements from Li to Ne), all elements have 2 valence electrons. However, the chemical reactivity of these valence electrons can change as you move across the row due to the increasing nuclear charge affecting their interactions with other atoms.
In a redox reaction the numbers of some of the elements changes from the reactants to the products?
In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.

What is identical in all elements?
In all elements, the number of protons and electrons is the same. Of course, both these numbers change with each element, but the ratio is always 1 to 1. The number of neutrons also changes, but can be the same in a few different elements due to isotopes.
Properties of elements change according to a pattern across the?
Groups of the Periodic Table of Elements.
