Looking for short lessons to keep your child engaged and learning? Our experienced team of teachers have created English, maths and science lessons for the home, so your child can learn no matter where they are.
And, as all activities are self-marked, you really can encourage your child to be an independent learner. You may have heard of atoms before, but what've they got to do with elements and compounds? Firstly, atoms are the basic building blocks of all matter on Earth and they're very tiny far too small to be seen with the naked eye. Substances can be categorised as either elements or compounds. Both of these are made up of atoms, the only difference is an element is made of one type of atom whereas compounds are made of two or more different types of atoms.
We're confident that if you follow the step-by-step guide below your child will be able to:. There are four keywords and definitions to get to grips within this topic. Once your child has got this, they'll find this topic much easier. An atom is the smallest particle that can exist. Everything is made from atoms. Atoms are shown in diagrams as small circles. An e lement is made up of o ne type of atom only.
For example, a piece of pure copper is made up of only of copper atoms. There are known elements on Earth and they are all listed in the periodic table. A compoun d is a substance made up of two or more atoms of d ifferent elements chemically joined or bonded together.
For example, carbon dioxide gas CO 2 consists of one carbon atom and two oxygen atoms bonded together. A molecule describes two or more atoms bonded together all compounds are molecules and some elements are too.
The atoms of some elements, like Neon, do not join together and instead exist on their own as individual atoms they are not molecules. The atoms of other elements, however, like Hydrogen join together as pairs, making a molecule. Imagine you are presented with diagrams of different substances? Atoms of the same element in diagrams will be drawn as the same size and they will be the same colour as shown in diagram 2. If the atoms are of different elements they will be a different colour or size as shown in diagram 3.
Elements and compounds are not always displayed as diagrams. Symbols are used to represent elements and each element from the periodic table has a symbol. This symbol can be made up of one or two letters but it always starts with a capital letter. For example, the symbol for nitrogen is N and the symbol for lithium is Li.
A formula is a shorthand way of showing the elements in a compound. The formula for sodium chloride is NaCl. This compound must be made up of two elements as there are two capital letters present in the formula. By consulting the periodic table you can discover that this compound is made up of one sodium atom Na and one chlorine atom Cl. Another compound, potassium oxide has the formula K2O.
It consists of two potassium atoms symbol K and one oxygen atom symbol O. Your child needs to ensure they take extra care when writing down the symbols of elements in the periodic table, paying close attention to whether the letters should be in upper or lower case.
For example, writing CO instead of Co completely changes the substance in question. Try these questions together to see if you can identify the differences between elements and compounds:.

Firstly, atoms are the basic building blocks of all matter on Earth and they're very tiny far too small to be seen with the naked eye. Substances can be categorised as either elements or compounds.
It will help them achieve more knowledge about the substances that play an important role in our lives. Such questions, as in this practice sheet, will not only help students assess themselves but will also help tutors to know the level of understanding in students. The worksheets consists of multiple choice questions, give-one-word-answer and match-the-following which makes it more interesting to solve. No credit card required, no obligation to purchase. Everything around us is made up of elements. They are the constituting factors for everything on this planet Earth: the tree, your book, your pencil, paper, and furniture, so on.
The basic building block of all matter, atoms are at the core of all that we see, touch, smell, feel, and taste. Molecules are formed when two or more atoms link up. A reasonable knowledge of atoms and molecules is indispensable for us to demystify the universe. Both substantially informative and excitingly illustratory, our atoms and molecules worksheets for grade 5 through grade 8 take students through all relevant aspects of the topic with such delicate attention for detail that by the end of the worksheets, learners leave thoroughly educated.

Но сообщать имена жертв… с точки зрения человека в очках в металлической оправе, это было признаком особой элегантности стиля. Его пальцы снова задвигались, приводя в действие сотовый модем, и перед глазами появилось: СООБЩЕНИЕ ОТПРАВЛЕНО ГЛАВА 26 Сидя на скамейке напротив городской больницы, Беккер думал о том, что делать. Звонки в агентства услуг сопровождения ничего не дали. Коммандер, недовольный необходимостью говорить по линии, не защищенной от прослушивания, попросил Дэвида не звонить, пока кольцо не окажется в его руках. Он решил было обратиться в полицию - может быть, у них есть данные о рыжеволосых проститутках, - но Стратмор на этот счет выразился недвусмысленно: Вы должны оставаться невидимым. Никто не должен знать о существовании кольца. Может быть, стоит побродить по Триане, кварталу развлечений, и поискать там эту рыжую девицу.
Халохот пробирался между деревьями с пистолетом в руке. Деревья были очень старыми, с высокими голыми стволами. Даже до нижних веток было не достать, а за неширокими стволами невозможно спрятаться. Халохот быстро убедился, что сад пуст, и поднял глаза вверх, на Гиральду. Вход на спиральную лестницу Гиральды преграждала веревка с висящей на ней маленькой деревянной табличкой. Веревка даже не была как следует натянута.
- Слово разница многозначно. Нам нужно число - значит, речь идет о математике. Еще одна игра слов мистера Танкадо: разница означает результат вычитания. - Верно! - сказал Беккер с экрана. - Может быть, у этих элементов разное число протонов или чего-то. Если вычесть… - Он прав, - сказал Джабба, повернувшись к Соши.
Очевидно, он ошибался.
