They don't HAVE to. Methane CH4 is an organic compound and (as you can see) isn't all that big. However the vast majority of them are large, into the hundreds if not thousands of atoms. DNA and protein chains can be exceedingly long.
No, the properties of individual atoms and the compounds they form are not always very similar. Atoms have unique characteristics based on their atomic structure, while compounds exhibit different properties that arise from the interactions between the atoms within them. The combination of different atoms in a compound can lead to new properties that are distinct from those of the individual atoms.
Carbon and organic compounds almost always contain hydrogen atoms. These two elements are commonly found together in organic molecules due to their ability to form stable covalent bonds, resulting in a wide variety of compounds.
Organic compounds always contain carbon atoms bonded to hydrogen atoms. Additionally, they may also contain other elements such as oxygen, nitrogen, sulfur, or halogens. The presence of carbon-hydrogen bonds is a defining characteristic of organic compounds.
they always contain glucose or atoms of sugar
Alkanes are always saturated hydrocarbons. They contain only single bonds between carbon atoms, making them fully saturated with hydrogen atoms.
No, compounds can contain the same type of atoms bonded together. These are called diatomic molecules, such as oxygen gas (O2) or nitrogen gas (N2), where two atoms of the same element are chemically bonded.
Organic compounds always contain carbon atoms, along with hydrogen atoms. Additionally, they may also contain oxygen, nitrogen, sulfur, phosphorus, or other elements commonly found in living organisms.
The basic building block of all compounds is atoms. Compounds contain atoms of at least two different elements bonded to one another. Thus, atoms of elements are what form compounds.
Elements contain only one type of atom (atoms with the same number of protons). Compounds contain more than one element, and thus contain atoms with different numbers of protons. Compounds can be converted into elements, but elements are not reducible to anything simpler (besides subatomic particles).
Organic compounds will always contain carbon atoms bonded to hydrogen atoms. Additionally, they may also contain other elements such as oxygen, nitrogen, sulfur, or phosphorus.
Carbon and hydrogen atoms are always found in organic compounds. Additionally, organic compounds may also contain oxygen, nitrogen, sulfur, or other elements in smaller quantities.
No, the properties of individual atoms and the compounds they form are not always very similar. Atoms have unique characteristics based on their atomic structure, while compounds exhibit different properties that arise from the interactions between the atoms within them. The combination of different atoms in a compound can lead to new properties that are distinct from those of the individual atoms.
Ionic compounds, metallic compounds, and intermetallic compounds do not contain covalent bonds. Ionic compounds form through the transfer of electrons between atoms, metallic compounds involve a sea of delocalized electrons shared between atoms, and intermetallic compounds consist of metal atoms with different electronegativities bonding in a specific crystal structure.
Carbon and organic compounds almost always contain hydrogen atoms. These two elements are commonly found together in organic molecules due to their ability to form stable covalent bonds, resulting in a wide variety of compounds.
Organic compounds always contain carbon atoms bonded to hydrogen atoms. Additionally, they may also contain other elements such as oxygen, nitrogen, sulfur, or halogens. The presence of carbon-hydrogen bonds is a defining characteristic of organic compounds.
All organic molecules contain carbon atoms.
All compounds contain more than one element and more than one atom.
