What defines the mass number of an isotope? What is the charge, in units of the electronic charge, of proton? How does an atom differ from an element? What determines an element's properties? How to determine valence electrons? What is an electron called in nuclear chemistry?
What defines a netbook? The netbook has always been better defined as a concept than by a series of specific size and weight specifications. That's because companies used the term netbook to describe a wide range of smaller-than-a-laptop systems, from models with 6"-7" displays (not much...
Thenumber of protons in an atomis called the 'Atomic Number' of that atom and is sometimes referred to as 'Z'. This is important because itdefines the type of atom, i.e. whichelementit is an atom of. Protonsandneutronsare collectively referred to asnucleons. ...
What is the atomic mass of an electron? What are the first 20 elements and their atomic numbers? Which isotope defines the atomic mass unit? What are the 3 parts of an atom? What element has a small atomic radius? Which subatomic particles contribute to an atom?s mass number but not it...
It's not to scale but helpful for understanding how an atom is built. A core nucleus of protons and neutrons is surrounded by orbiting electrons. Every atom must have at least one proton in it. The number of protons in an atom is important, because it defines what chemical element the ...
Which quantum number defines the shape of an orbital? How many electrons can be held in the second orbital? What is the orbital diagram for nobelium? How many electrons are there in an atom of carbon? How many electrons does carbon have?
What specifically defines a cotransporter as an antiporter? A. Both molecules are imported into the cell. B. Both molecules are exported out of the cell. C. Both molecules move down their concentration gradients. D. One molecule is transported against its ...
If an atom absorbs some energy, an electron in an orbital close to the nucleus (a lower energy level) will jump to an orbital that is farther away from the nucleus (a higher energy level). The atom is now said to be excited. This excitement generally will not last very long, and ...
What defines an isotope? An isotope is defined by its number of neutrons, differing among atoms of the same element. 10 What role do isotopes play in medical imaging? Radioactive isotopes are used in medical imaging to diagnose and monitor various diseases. 8 Can isomers be separated easily?
A neutral particle in the nucleus of an atom. Neutrons contribute to the mass of an atom but not its charge. 11 Proton A positively charged particle in an atom's nucleus. The number of protons defines the atomic number of an element. 6 Neutron Acts as a nuclear 'glue.' Neutrons help ...
