What is meant by an element?
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
What always stays the same in a compound?
a compound always has the same chemical formula
How is matter organized into substances mixtures elements and compounds?
Matter is organized into substances, which are either mixtures (combination of two or more substances) or pure substances. Pure substances can be elements (composed of all the same type of atom) or compounds (composed of different types of atoms bonded together in fixed ratios). Elements cannot be further broken down by chemical means, while compounds can be broken down into simpler substances by chemical reactions.
Can you have two elements with the same atom?
Yes, two elements can have the same type of atom if they have the same number of protons. Isotopes are atoms of the same element that have different numbers of neutrons, but the same number of protons.
Examples of the law of definite composition?
The law of definite composition states that chemical compounds always contain the same elements in the same proportions by mass. For example, water always consists of two hydrogen atoms and one oxygen atom in a 2:1 ratio by mass. Additionally, carbon dioxide always contains one carbon atom and two oxygen atoms in a 1:2 ratio by mass.
Are compounds of the element?
The elements of a compound are the chemical bonds that are present in a specific ratio in a compound. Elements are pure chemical substances that are made of the same atom.
What is the difference between Isomorphic mineral and polymorphism?
Isomorphic minerals have the same chemical composition but different crystal structures, while polymorphism refers to minerals that have the same chemical composition and crystal structure but different crystalline habits. Essentially, isomorphic minerals differ in their arrangement of atoms within the crystal lattice, while polymorphic minerals have the same atomic arrangement but different shapes or forms.
Why is an atom different from and element?
Element are the pure substances that contain atom of same kind. Atoms are fundamental particles of matter.
Which type of substances is composed of two or more differant kinds of elements always in the same ratio?
compound
Which type of substances is composed of two or more different kinds of elements always in the same ratio?
compound
In atoms electrons and protons are in the same ratio or different ratio?
protons and electrons are identical in number in an atom
Why do they say an atom is the smallest particle of an element that can not be split into two or more substances and at the same time say that an atom is comprises electrons protons and neutrons?
Atom is the simplest part of the matter in a chemical sense; by physical methods we can break an atom.
Are sodium chloride and potassium chloride isomorphic?
Yes, sodium chloride (NaCl) and potassium chloride (KCl) are isomorphic compounds because they have the same crystal structure and similar physical properties. Both compounds belong to the same crystal system and share similar bonding characteristics due to their similar ionic sizes and charges.
How can you describe figures that have the same shape and are the same size?
equal, the same as, mathmatically similar, exactly the same as each other etc. The technical term for figures of identical size and shape is "isomorphic".
When both NH2 and COOH replace hydrogen atoms on the same carbon atom a(n) is formed.?
These substances are called aminoacids.
What is meant by an element?
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
What is the ratio of elements in a compound?
The ratio of elements in a compound is determined by the number of atoms of each element present in the compound. This ratio is represented by the chemical formula of the compound, showing the types and numbers of atoms involved in the chemical bonding.
