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.
What else can I help you with?
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 difference between group and period in periodic table?
Groups are vertical columns on the periodic table consisting of elements with the same number of valence electrons. Periods are horizontal rows with elements sharing a highest unexcited electron energy level.
What is true about the properties of the elements in any one period of the Periodic Table?
All of the elements in any one period of the Periodic Table have the same number of valence electrons.
How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How do the number of electrons change across the period of elements?
they get more electrons the farther right the get
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).

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.
Properties of elements change according to a pattern across the?
Groups of the Periodic Table of Elements.
How does the number of valence electrons change as you go across the 2nd period of the periodic table?
the no. of electrons increses
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.
Do Atoms have no overall eletric charge?
Elements, as they appear on the Periodic Table, have no net charge. They all have equal numbers of protons (+) and electrons (-). HOWEVER, an atom can gain or lose electrons, which will change its charge, but, again, on the periodic table, they all have 0 charge.
