Insert the chemical symbol in the answer blank for each of the following elements

A balanced 'picture' equation which helps you understand reading formulae and atom counting to balance the equation. The fully written out symbol equation with state symbols often optional for starter students. For any reaction, what you start with are called the reactants, and what you form are called the products.

Atoms and elements An atom is the smallest building block of everything that exists. The smallest object you can see under a microscope has more than 10 billion atoms.

Insert the chemical symbol in the answer blank for each of the following elements

There are over a hundred different types of atoms, that we call elements. They form the world we live in. Well known elements are hydrogen, oxygen, iron or lead. When two elements get together they form a compound.

For example, water has two atoms of hydrogen and one atom of oxygen. Atoms all have about the same size, but they have different weights.

Mixed Elements Trivia and Quizzes

Plutonium is one of the heaviest atomsabout times heavier than hydrogenwhich is the lightest element. Parts of the Atom An atom consists of three parts: Protons and neutrons are in the centre of an atom, which is called the nucleus. If an atom had a diameter of about 6 km the nucleus would only be as big as a tennis ball.

The rest of the atom outside the nucleus is mostly empty. Electrons fly around in an atom very, very quickly. They have almost no mass and travel around the nucleus millions of times every second.

The parts of an atom have electrical charges. Each proton carries a positive electrical charge and each electron has a negative electrical charge. Neutrons have no charge. In most cases an atom has the same number of protons and electrons. It is electrically neutral.

The energy of the nucleus keeps the electron inside the atom—just like the Earth keeps the moon in its orbit. But electrons have energy themselves.

Insert the chemical symbol in the answer blank for each of the following elements

Chemical names are given to elements as they are discovered. Sometimes these are written in periodic tables, but often times the chemical symbol - or the shorthand name of that particular element. Elements differ from each other in the number of protons they have, e.g.

Hydrogen has 1 proton; Helium has 2.

Key Questions

The neutron also is located in the atomic nucleus (except in Hydrogen). The neutron has no charge, and a mass of slightly over 1 amu. May 17,  · Insert your symbol into a Microsoft Word document.
