What is the element indium?
indium (In), chemical element, rare metal of main Group 13 (IIIa, or boron group) of the periodic table. Indium has a brilliant silvery-white lustre. It was discovered (1863) by German chemists Ferdinand Reich and Hieronymus Theodor Richter while they were examining zinc ore samples.
How do you find the electrons?
Finding the Number of Electrons The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.
What has 18 protons 22 neutrons and 18 electrons?
Argon The chemical symbol for Argon. A 2 dimensional representation of a Argon atom with 18 protons and 22 neutrons in the nucleus and 18 electrons orbiting the nucleus.
How many electrons are in an element?
Finding the Number of Electrons The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.
How do you find the number of electrons in a charge?
The charge on the ion tells you the number of electrons. If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more protons. If the charge is negative, add the amount of charge to the atomic number to get the number of electrons.
What has 16 protons and 18 neutrons?
So, if there are 16 protons, the element must be sulfur. The mass number for this isotope is 34 – there are 16 protons and 18 neutrons.
How do you find the number of electrons?
The number of electrons in a neutral atom is equal to the number of protons. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
How do u find electrons?
Finding the Number of Electrons The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.
How do you find electrons on the periodic table?
Electron configurations and the periodic table. Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.
What has 16 protons and electrons?
If a sulfur atom has 16 protons, 16 electrons, and 16 neutrons, what is its atomic mass?
How many electrons are in each element?
Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146)….2.1 Electrons, Protons, Neutrons, and Atoms.

How do you convert atoms to electrons?
Multiply the element's atomic number by the number of atoms of this type (see Step 1) in the molecule. Repeat for all elements in the molecule, then add up all the products to calculate the number of electrons. In the first example, the number of electrons in KNO3 equals (19 x 1) + (7 x 1) + (8 x 3) = 50.
Are electrons and protons the same?
Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).
How many electrons are in each shell?
The first shell (closest to the nucleus) can hold two electrons. The second shell can hold 8 electrons. The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.
What has 16 protons and 18 electrons and 18 neutrons?
So, if there are 16 protons, the element must be sulfur.
How do you find number of electrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
How do you find the total number of electrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

How do you find the number of free electrons?
The calculation is involved even for a crude model, but the result is simple: g(E)=πV2(8meh2)3/2E1/2, where V is the volume of the solid, me is the mass of the electron, and E is the energy of the state. Notice that the density of states increases with the square root of the energy.
What are free electrons in metals?
Solution : Atoms in metals have one or more electrons which are loosely. Bound to the nucleus. These electrons are called free electrons and can be easily detached from the atoms by applying small energy.
