The secret of matter
composition of atoms
The composition of atoms:
Atom (non-electroelectric)
Nucleus (positively charged)
Proton (a proton carries one unit of positive charge)
Neutron (uncharged)
Electron (an electron carries one unit of negative charge)
Atomic mass calculation
Electrons in atoms (see example on the right)
element
Elements and element symbols
Made of elements
Pure substances composed of the same element
A pure substance composed of two or more elements is a compound
element symbol
In order to facilitate communication, it is internationally stipulated that each element is expressed by a unified symbol. This symbol is called an element symbol.
periodic table of elements
The periodic table of elements was created in 1869 when the Russian chemist Mendeleev arranged the 63 elements discovered at that time from smallest to largest to form the original periodic table of elements.
Representation of material composition
Chemical formulas and their meanings
A formula consisting of element symbols and numbers representing substances is called a chemical formula
An element can be from:
Explain macroscopically
explain microscopically
Valence
Valence represents the number of electrons gained and lost by atoms when they combine with each other.
Valence is also a property that an element exhibits when forming a compound
Notice!
1. In a compound, calculate the valence of the specified element based on the sum of the positive and negative valence algebras being zero.
2. Clearly mark the valence of the element directly above the element, always with a positive or negative sign.
3. When oxygen appears, the oxygen element is written next.
4. In compounds composed of metals and non-metals, when writing chemical formulas, the element symbols of the metal elements are written in front and the element symbols of non-metal elements are written in the back.
