Group and Period

[605823283]

Hi! I always get group and period mixed up of which is the row and which is the column. Does anyone have any good ways to remember it? Any good mnemonics for it? Thank you!!!

Hi!

I don't know if this will work for you but the way I remember it is that the words group, down, and column all start with letters in the beginning of the alphabet(G, D, and C) and then row and period start with letters towards the end, or at least just not at the beginning (P and R). I also though that you could use GCPR, or Good Cats Pursue Rats, which is just group column period row.

Hope this helps!

I just thought of this but the rows on the periodic table contain more elements than the columns and the word “period” is longer than the word “group” in terms of the number of letters. Other than that, I can’t think of anything else.

[Bela Patel 2B]

I have no tricks to remember the period but, to remember which one is the group, I think of the columns of the Noble Gases, Halogens, etc. and I think of them as “groups” of elements.

Hi! I always think of it as periods are used to end sentences and sentences are horizontal -> periods are horizontal. Groups are the opposite, so vertical.

[Michelle Jeong 1B]

The groups are the columns and the periods are the rows. I remember the groups by thinking of the noble gases as a group and those go down the column.

The word "period" is longer than the word "group." Similarly, the periods (aka the rows) in the periodic table stretch longer than the groups (aka columns) do. So, that's one way to remember period vs. group.

[Shannon Clark 1F]

It may be silly, but I remember it because periods end sentences and sentences are read horizontally! Then that leaves groups to be the columns. Hope it helps you too! :)

This isn't the most catchy way, but groups of atoms have similar properties. Once you realized that the last column of the periodic table has atoms with a full valence shell, it tends to make sense that the columns is what group atoms. Atoms have similar properties because they have the same amount of electrons in their valence shells, which is what columns of atoms have in common.

I just remember columns being like pillars so they are vertical and then periods are horizontal like reading.

When I think of group, I think of how there are different groups of elements on the periodic table like noble gases. Noble gases are grouped together in a column down the periodic table and that helps me remember group. By remembering that groups are the columns in the periodic table, then I know that the periods are the horizontal rows.

[Madison Nguyen 3L]

The groups are found via columns and the periods are found via rows. Generally, groups can be remembered by thinking of noble gases as a singular column.

If I ever get stuck, I think of it in terms of the fact that the word period is longer than the word group, and the width across a period is much longer than the height down a group. Also, the periods go left to right horizontally, and periods go at the end of sentences, which you write left to right horizontally! Maybe that will help haha!

[cherublina1l]

I think of periods as coming at the end of the sentence and since sentences are horizontal it's the row (also helps if you think of the row as a horizontal boat/canoe that you need to row haha)

[Eric Sun 2G]

I think of period as like a period of time, where it looks like a time line that goes horizontally across.

Columns/groups are vertical and periods are horizontal. You can remember it by thinking about a column in a newspaper: it vertically proceeds as it goes on.

I remember periods are going horizontally by thinking of P in periods and H in horizontally making "Ph." Hope this helps!

[Julia Zahra]

groups are the columns and periods are the rows.

[noahbehrendt2L]

I always remember that groups are the columns because both words have "o" and "u". If you know which one the groups are then you also know that the rows are horizontal.

[Marie Khijniak 2E]

Hi!
This might not be very helpful, but I always think of doing something “periodically,” and when you do something periodically such as read words on a page, you go from left to right. You can also think of a group as a small group of friends, groups being smaller than periods in number of elements.
Hope this helps!

Periods are horizontal, so the first row is period 1 second is 2 and so on. The groups are vertical and I associate them with metals, gases, liquids!

[Colby Irvine 2A]

A column is generally a more vertical group and a period is like reading left to right, so horizontal.

I think of "groups go down." If groups go down, they also have to travel upwards, and periods have to be the opposite to groups, therefore they must be horizontal.
