What else can I help you with?
What characteristics must two elements share if they are in the same period?
Elements in the same period share the same number of electron shells. This means they have similar atomic sizes and properties because they have the same number of electron shells determining their size and behavior.
What do the elements have the same number of as you move left to right?
electron shells
The rows going across the periodic table is known as periods and contain elements with the same number of?
The rows going across the periodic table are known as periods and contain elements with the same number of electron shells.
Do horizontal rows on the periodic table have the same amount of protons or same number of electron shells?
Atoms whose symbols appear on a single row of a periodic table have the same number of electron shells. (Atoms with different numbers of protons represent different elements.)
Paired electrons are represented by what dots?
An electron pair are two electrons which occupy the same orbital in an atom or molecule. Paired electrons are represented by two dots.
What Elements in the same row are filling up the same energy level as you move from left to right?
Elements in the same row, or period, of the periodic table fill up the same energy level as you move from left to right. This is because elements in the same period have the same number of electron shells.
Which have more electron shells oxygen or sulfur?
Both oxygen and sulfur have the same number of electron shells, which is two.
What characteristics must two elements share if they are in the same period?
Elements in the same period share the same number of electron shells. This means they have similar atomic sizes and properties because they have the same number of electron shells determining their size and behavior.
The periods in the Periodic Table have the same number of what?
They have the same number of electron shells.
Do elements in the same column of the periodic table have the same number of electron shells?
Yes
Do all alkaline metals have 2 electron shells?
No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.
Why is electron shielding not a factor when you examine a trend across a period?
Electron shielding is not a factor across a period because they all have the same number of electron shells! No further (extra) shells means that they are all affected by electron shielding equally.
As you move across a period elements have the same number of?
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
Does sulfur have more electron shells than oxygen?
Yes sulfur does have more electron shells than oxygen.
What do the elements have the same number of as you move left to right?
electron shells
What ions have the same electron configuration as helium?
Lithium ion (Li+) and beryllium ion (Be2+) have the same electron configuration as helium because they both have filled electron shells.
The rows going across the periodic table is known as periods and contain elements with the same number of?
The rows going across the periodic table are known as periods and contain elements with the same number of electron shells.
