Chemists use equivalent units, or equivalents, to express the reactive capacity of a chemical species, such as electrons or ions like H+. The equivalent defines how many electrons or ions may be transferred in a chemical reaction. For example, in the aci
Determine how many electrons the atom has lost or gained. Elements in column 1 of the periodic table (e.g., sodium and potassium) will lose an electron when they react, while elements in the second column (e.g., calcium, magnesium and strontium) will generally lose two electrons when the...
How do you write a compound which contains calcium (Ca) and the polyatomic ion chlorate (ClO3)? How do you tell how many valence electrons there are in an element by looking at the periodic table? What is the formula for finding out how many electrons an element has? What is an Atomic...
How many electrons does cobalt have? Cobalt Cobalt is a transition metal that is located in the first row of the transition metals. Its atomic mass is 58.933 g/mole and is used to make blue pigments. The largest mining operations for cobalt are in Central Africa. ...
How many hydrogen atoms is the carbonyl group bonded to? How many hydrogen atoms would have the same mass as one calcium atom? How many valence electrons does Hydrogen have? How many bonds does selenium have with hydrogen? How many atoms can be on one element? How many atoms are in oxy...
The problem is that X-rays are a form ofionizing radiation. When normal light hits an atom, it can't change the atom in any significant way. But when an X-ray hits an atom, it can knock electrons off the atom to create anion, an electrically charged atom. Free electrons then collide...
electrons, or six electrons in its outermost orbital. You can also figure out how many electrons are in its first, second and third orbitals: The first orbital can hold a maximum of two electrons, while the second has four suborbitals and so can hold a total of eight electrons. The third...
How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example, hydrogen atoms have one electron orbiting the nucleus. Helium atoms have two electrons orbiting the nucleus. Aluminum atoms have 13 electrons circling the nucleus. Each atom has a preferred number of ...
Answer to: How many valence electrons does S have? Periodic Element S Atoms have several layers, with the nucleus at the center and electrons surrounding it. Electrons on the outermost layer, or shell, of the atom, are called valence electrons. How many they have and how they are arranged...
In 1913, Bohr proposed that electrons exist in discrete orbits based on their energy. When an electron jumps from one orbit to a lower orbit, it gives off energy in the form of a photon. The quantum theory of light -- the idea that light exists as tiny packets, or particles, called ...
