The only way to break gold down into smaller components would be through nuclear reactions that change the number of protons and electrons, the positively and negatively charged particles, inside the gold atoms. Gold is characterized by having 79 protons and, in its elemental or uncharged state, also has 79 electrons.

The element carbon comes in three different natural forms, or allot ropes : diamond, graphite, and amorphous. Diamonds are formed under extreme pressure and heat, 100-200 kilometers below the Earth's surface, by bonding carbon into a three-dimensional crystal network.

Graphite differs from diamonds in that the carbon atoms are bonded into flat sheets, creating a black, slippery substance that is one of the softest substances known to man. Carbon also exists in the isotope carbon-14, with 8 neutrons, but this form is unstable (a radioactive isotope) and decays into nitrogen-14 over time by releasing an electron and converting a neutron into a proton.

The word ferric refers to iron ions with a +3 charge (or with 23 electrons), whereas ferrous refers to iron ions with a +2 charge (or with 24 electrons). Rust forms when the oxygen in air or in water combines with iron, which is a major component of steel, for example.

Rust is a compound because it is made up of two chemical elements, usually iron and oxygen. Iron oxide(rust), sodium chloride(salt), etc.

In a mixture, the atoms can be separated from each other by physical means, such as dissolving or filtering. In a compound, the atom can only be separated from each other by chemical means, such as heating or reacting with an acid.

If hydrochloric acid poured on a rusty nail, the rust will become iron chloride. Place a rusty nail in cup filled with distilled white vinegar.

In a few minutes, the color of the vinegar will become a yellowish orange. FYI you can make thermiteout of it, just add 1\3 aluminum powder.

Sep 13, 2017 Maybe I'm out of touch and need to go back to school. When I read this I consider rust (if Fe2O3) as a pure substance. When I read nickel I read 5 cent pieces and that isn't pure.

A company produces fruity drinks that contain a percentage of real fruit juice. Drink A contains 10% real fruit juice and Drink B contains 30% real fruit juice.

The health triangle is made up of(choose all that apply)? A fruit drink is made by mixing juice and lemonade in the ratio : 1 : 4 (juice : lemonade) Juice costs £6.00 per liter.

James has to choose his options in his final year at school. He must choose one subject from each of five different option groups.

Is rust (Fe2O3) a pure substance or a mixture? When a piece of metal corrodes, the electrolyte helps provide oxygen to the anode.

When a drop of water hits an iron object, two things begin to happen almost immediately. As the acid is formed and the iron dissolved, some water will begin to break down into its component pieces -- hydrogen and oxygen.

The chemical compounds found in liquids like acid rain, seawater and the salt-loaded spray from snow-belt roads make them better electrolytes than pure water, allowing their presence to speed the process of rusting on iron and other forms of corrosion on other metals. They can be made harder by adding another element to the pure metal, so forming an alloy.

The greater the force needed, the harder and stronger the metal.

In a pure metal, the force needed to make the layers slide over each other is small. This means that a greater force is required for the layers to slide over each other.

The metal lattice structure is distorted in alloys Question Explain why steel, which is an alloy of iron, is harder than pure iron. Reveal answer Steel contains atoms of other elements as well as iron.

Recognize the difference between physical and chemical, and intensive and extensive, properties Extensive properties, such as mass and volume, depend on the amount of matter being measured.

Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance ’s chemical identity.

Chemical property characteristic that can be determined only by changing a substance ’s molecular structure. Intensive property characteristic of matter that does not depend on the amount of the substance present.

Physical property characteristic that can be determined without changing the substance ’s chemical identity. Extensive properties, such as mass and volume, depend on the amount of matter that is being measured.

Intensive properties, such as density and color, do not depend on the amount of matter. Physical properties Matter has mass and volume, as demonstrated by this concrete block.

The preferred oxidation state is the lowest-energy oxidation state that a metal will undergo reactions in order to achieve (if another element is present to accept or donate electrons).
