What are the two main parts of an atom of an element? What is an atom? What are the basic parts of an atom? What does an atom of lead look like? What are the parts that compose of the atom? What are two ways in which the elements with atomic numbers 12 and 15 are different?
Every element is made of atoms—piles of paper clips. All atoms of any element are the same—all the paper clips in the pile are the same size and color. Atoms of different elements are different in size and properties—like different sizes and colors of paper clips. Atoms of different ...
If you know where a certain element sits in the table, and you know a little bit about the properties of the elements above, below, and either side, you can often figure out what the properties of that element will be.How do atoms make molecules and compounds? Atoms are a bit like ...
Element X has a face-centered cubic unit cell structure. If the density of the element is measured to be 12.4 g/cm^3, what is the atomic radius of X? units are in pm (picometers) How does the measuring device determine the number of significant figures in a measurement?
When a chemical reaction takes place to combine two or more electrons into one or more compounds, the electrons of the atoms of each element interact with each other. However, the reaction does not affect the atoms' nuclei. States of matter ...
‘concept’ stems from the fact that in the past they have been both. But does a new element really have quite the same claim to reality when it exists only as a handful of atoms that are stable for less than a second, as is the case with some of the newest artificial elements, ...
5.A molecule that does not have a positive end and a negative end is called a ___ molecule.6.Lithium,a group 1 element with an electron configuration of 1s22s1,will form a ___ ion in a chemical reaction.7.Given the following balanced reaction between nitrogen gas and oxygen gas to p...
It can also occur at a molecular level, due to changes in the orientation of electrically polar molecules in response to an applied field, or through bending & stretching of the bonds between atoms within a molecule, very much like the material in a mechanical spring is bent or stretched. ...
There’s one more element we use in quantum computers - entanglement. This is a special link between quantum systems that can only be described using quantum physics. In a sense when two objects - like qubits - become entangled, they can’t really be described as two objects any longer. ...
Like hydrogen, it is a colorless and odorless gas. However, it is an unreactive element, and the lightest of the group called the "noble gases." It therefore doesn't play a role in biology, and isn't used in many chemical processes in industry (aside from as an inert substance), ...
