B0BSM1TH studies the periodic table.

Hey everyone! As a student, you've probably seen or dealt with the Periodic Table. If not, it's one of the most confusing science things ever! My science teacher has worked with my class for about three weeks now, and I know how hard it is to study it. I've collected tips for how the table is organized, what all the letters are for, and all the other things of the Periodic Table of Elements.

First, let's see how this table is organized. In 1869, Dmitri Mendeleev organized the most understandable periodic table. He knew there were more elements to be found, so he left spaces for unknown elements. He organized the elements based on their number of protons and electrons (FYI, the protons and neutrons are what makes up the nucleus, and the electrons are the things around it flying around). If you look at the periodic table, you will see sideways rows, and vertical columns. The rows are called periods, and the columns are families, or groups.

Ang3lcat informs about Iqbal Masih and child slavery.

"The International Labor Organization (ILO) has estimated that 250 million children between the ages of five and fourteen work in developing countries -- at least 120 million on a full time basis." Most of these children, 61%, work in Asia, while 32% work in Africa and 7% in Latin America. The majority of these children work in agriculture, either helping out their family or being forced to do it. They also work in trade and services, domestics, manufacturing, construction, as well as others. Some of these kids are just helping out their families or friends while others are trying to get a little more money. The ones left over, however, are working for a much darker cause.

It's called slavery. Even though it is outlawed by the United Nations, it is happening all around the world. People that have slaves keep them hidden, of course. This being so, it is hard to determine exactly how many people are slaves. It's estimated that 60 to 115 million children work in India alone. Fifteen million of these are not getting paid at all. They work in carpet, brick, and silk making, harvesting cocoa, cotton, and sugar cane, even the army, as well as many other areas. While many organizations are trying to stop this, it doesn't seem to have much of an effect. Children are still being forced to work.
