The properties of matter depend on the types of atoms that matter is made of. Matter can exist in two forms. It can be a pure substance. This means it is not mixed with anything. It can also be a combination of different substances. This means it can be a mix of different types of atoms. You may recall that atoms differ based on the numbers of protons they contain. Some atoms contain only one proton such as Hydrogen. Other atoms contain many protons. There are many types of atoms. For example, Helium has two protons. An Oxygen atom has eight. Water is composed of a two types of atoms. Water is made of two Hydrogen atoms and one Oxygen atoms. There are only so many types of atoms. These atoms can be mixed into an almost limitless amount of substances. So what do we call a substance that has only a single type of atom?

How many protons do atoms contain?

Powell contended that it was not inconsistent to want to foster cooperation even with an organization like the Indonesian military, which has a history of human rights abuses. "If you get young officers, expose them to a military organization that is within a democratic political institution, such as the United States, then that rubs off on them," he said. In Malaysia, Powell met with Prime Minister Mahathir Mohamad, who has led the country since 1981. The Malaysian foreign minister, Syed Hamid Albar, later told local reporters that Powell had proposed that American and Malaysian officials review the idea of forming a regional training center in Malaysia to coordinate antiterrorism activities. His brief stop in Malaysia also highlighted the moral ambiguities of the effort to prevent terrorism and its emphasis on cooperation with governments that the United States has often criticized. The United States once distanced itself from Mahathir for strong-arm tactics with political rivals, and human rights groups criticize him for arresting and jailing scores of suspected militants, including some who may be linked to al-Qaida, without trial. Powell said his discussions with Mahathir "touched on the case" of his former deputy, Anwar Ibrahim, who is serving a 15-year sentence on charges of sodomy and abuse of power after trials that Powell said the United States had "always felt" were flawed. The assistant secretary of state for East Asian and Pacific affairs, James Kelly, met on Tuesday morning with Anwar's wife, Wan Azizah Wan Ismail, for what she later told Malaysian reporters was a discussion about both the detention of her husband and six supporters, and the campaign against terrorism.

Does Powell think America should work with other governments on counterterrorism efforts, even if those governments have a history of human rights abuses?

Electric charge is a physical property. It occurs between particles or objects. It causes them to attract or repel each other. They do not even have to touch. This is unlike the typical push or pull you may be familiar with. All electric charge is based on the protons and electrons in atoms. A proton has a positive electric charge. An electron has a negative electric charge. Forces on Charged Objects Most atoms are balanced electrically. They have the same number of positive and negative charges. Therefore, the number of protons equals the number of electrons. Neutrons do not matter as they have no charge. When an object loses some electrons, it becomes positively charged. There are now more protons than electrons inside the atom. The lost electrons may remain free. Or, they may attach to another object. The new object now has more electrons than protons. It then becomes negatively charged.
How will increasing neutrons affect the particle's charge?
