The early periodic tables were incomplete and some elements were placed in inappropriate groups if the strict order of atomic weights was followed. Mendeleev overcame some of the problems by leaving gaps for elements that he thought had not been discovered and in some places changed the order based on atomic weights. Elements with properties predicted by mendeleev were discovered and filled the gaps.

All atoms of a particular element have the same number of protons. Atoms with of different elements have different numbers of protons. You should be able to use the atomic model to describe atoms. Atomic Structure - detailed notes revision Notes.1.5 size and mass of atoms (common content with physics) (revision notes summary for aqa 9-1 gcse combined Science Trilogy: Chemistry paper 3, topic 8 "Atomic structure and the periodic table appreciate that atoms are extremely small, having. The radius of a nucleus is less than 1/10 000 of that of the atom (about 1 x 10-14 m). Almost all of the mass of an atom is in the nucleus. You must know the relative masses of protons, neutrons and electrons. The sum of the protons and neutrons in an atom is its mass number.
Details of these experiments are not required. Be able to describe the difference between the plum pudding model of the atom and the nuclear model of the atom. Details of experimental work supporting the bohr model are not required. Details of Chadwicks experimental work are not required. Atomic Structure - detailed notes revision Notes.1.4 Relative electrical charges of subatomic particles Know the relative electrical charges of the particles in atoms: proton, neutron and electron. In an atom, the number of electrons is equal to the number of protons in the nucleus. Atoms have no overall electrical charge. The number of protons in an atom of an element is its atomic number.

The discovery of the electron led to essay the plum pudding model of the atom. The plum pudding model suggested that the atom was a ball of positive charge with negative electrons embedded. The results from the rutherford and Marsdens alpha scattering experiments led to the plum pudding model being replaced by the nuclear model. Niels Bohr adapted the nuclear model by suggesting that electrons orbit the nucleus at specific distances. The theoretical calculations of Bohr agreed with experimental observations.
Later experiments led to the idea that the positive charge of any nucleus could be subdivided into a whole number of smaller particles, each particle having the same amount of positive charge. The name proton was given to these particles. In 1932 the experimental work of James Chadwick provided the evidence to show the existence of neutrons within the nucleus. This historical context provides an opportunity for you to show an understanding of why and describe how scientific methods and theories develop over time. You proprietorship should be able to: be able to describe why the new evidence from the scattering experiment led to a change in the atomic model.

There are about 100 different elements. Elements are shown in the periodic table. Compounds are formed from elements by chemical reactions. Compounds contain first two or more elements chemically combined in fixed proportions and can be represented by formulae using the symbols of the atoms from which they were formed. Compounds can only be separated into elements by chemical reactions. Chemical reactions can be represented by word equations or equations using symbols and formulae. You will be supplied with a summary periodic table for the exam and you should be able to: be able to use the names and symbols of the first 20 elements in the periodic table, the elements in Groups 1 and 7, and other elements.
