Flashcards

What are the fundamental building blocks of an atom?

Protons, neutrons, and electrons are the three main particles that make up an atom. They are responsible for the atom's chemical and physical properties.

What happens when electrons transfer between atoms?

When electrons move from one atom to another, they leave behind a positive charge on the atom they left and create a negative charge on the atom they joined.

What is a positive charge imbalance?

An object gains a positive charge when it has more protons than electrons. This imbalance occurs due to the loss of electrons.

What is a negatively charged object?

When an object has more electrons than protons, it becomes negatively charged. This difference in the number of electrons and protons creates a net negative charge.

What is the primary cause of static electricity?

Static electricity arises from the buildup of electrical charges on the surface of an object due to the transfer of electrons through rubbing or contact between objects.

What is the charge of an electron?

Electrons are negatively charged particles in an atom. They orbit the atom's nucleus.

What happens to atoms when they gain electrons?

When electrons leave their atoms and attach to others, the atoms become negatively charged due to the gain of negative charges.

What is static electricity?

Static electricity is a phenomenon caused by the buildup of electrical charges on a surface. It occurs when there is an imbalance of electrons and protons.

What essential knowledge is needed to understand static electricity?

To understand static electricity, it's crucial to first grasp the nature of matter, particularly the behavior of electrons within atoms.

What are the smaller particles that form atoms?

Protons and electrons make up the smallest particles that constitute atoms. Together, they contribute to the atom's overall charge.

How is the balance of electrons maintained in an atom?

The weak bonds between electrons in an atom create a balanced state. This balance is maintained as long as there is no significant external force acting on the electrons.

What is static discharge?

Static discharge, often referred to as a 'static shock', is a sudden transfer of electrical charge from a point of high potential to a point of low potential. It can occur when a statically charged object comes close to a neutral object.

What determines a material's conductivity of electricity?

The ability of a material to conduct electricity depends on the ease with which electrons can move within its structure. This ease of electron movement determines whether a material is a conductor or an insulator.

How does friction contribute to static charge buildup?

A static charge buildup can occur when surfaces with different electrostatic properties are rubbed together. This rubbing causes electrons to transfer from one surface to another, creating a charge imbalance.

Study Notes

###结构 الذرة

  • الذرة تتكون من ثلاثة جسيمات أساسية هي البروتونات والنيوترونات والإلكترونات
  • البروتونات والنيوترونات موجودة في النواة بينما الإلكترونات تدور حولها

الشحنة الكهربائية

  • عندما تترك الإلكترونات ذراتها وتلتصق بذرات أخرى، تنتقل الشحنة الكهربائية
  • عندما ي Become جسم ما أكثر بروتونات من إلكترونات، يصبح شحنه موجبًا
  • عندما ي Become جسم ما أكثر إلكترونات من بروتونات، يصبح شحنه سالبًا

الكهرباء الساكنة

  • السبب الرئيسي للكهرباء الساكنة هو نتيجة لانتقال الإلكترونات بين الذرات
  • من الممكن أن يصعقك دون تحذير في أي لحظة بسبب الكهرباء الساكنة
