What else can I help you with?
Is it true that an oxygen molecule has two atoms?
Yes, that is correct. An oxygen molecule consists of two oxygen atoms bonded together.
For atoms of most elements the outer energy is filled when it has 8 electrons true or false?
true
What is true of an atoms's nucleus?
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
Ozone is a form of oxygen true or false?
It is true. Ozone is an allotrope of oxygen.
When iron rusts iron atoms are destroyed True False?
False, iron atoms are converted to iron oxide
Is it true that when atoms form bonds electrons may be transfered or shared between atoms?
true
Is it true the size of a mole of atoms has a reasonable mass?
is it true the size of a mmole of atoms has a reasonable mass
Is it true that all atoms have the same mass?
It is not true !!
True or falseAn atom is always considered an element?
True. Atoms are the smallest units of an element therefore making all atoms elements.
When balancing a chemical equation the number of H atoms in 2 CH4 is eight is this True or false?
True. In 2 molecules of CH4, there are a total of 8 hydrogen atoms because each CH4 molecule contains 4 hydrogen atoms.
Is it true or false that atoms in a gas move more rapidly than atoms in a liquid or a solid do?
True. Atoms in a gas have higher kinetic energy and move more rapidly than atoms in a liquid or solid due to the greater distance between them and the weaker intermolecular forces present in gases. This leads to gases having more freedom of movement compared to the more constrained motion of atoms in liquids and solids.
Is this true or false an oxygen molecule usually has 2 oxygen atoms?
True. An oxygen molecule typically consists of two oxygen atoms.
Is it true or false that Chemical reactions rearrange atoms but do not create or destroy them?
True. In a chemical reaction, atoms are rearranged to form new substances, but the total number of atoms present before and after the reaction remains constant. This is known as the Law of Conservation of Mass.
True or false the phrase crystal structure refers to the repeating patterns in which atoms are arranged in a crystal?
False. In a crystalline structure, atoms are in an orderly arrangement.
Is it true that an oxygen molecule has two atoms?
Yes, that is correct. An oxygen molecule consists of two oxygen atoms bonded together.
What do most atoms have equal parts of?
Protons and Electrons. Furthermore this is true of ALL atoms not "most".
Organic compounds contain carbon atoms that are covalently bonded to other elements typically hydrogen and oxygen and other carbon atoms True or False?
true
