What happens to an atom if it loses an electron?
If an atom gains an electron, it becomes an anion, which is negative. Anions are larger than the original atom because of the added electrons. N + electron(-) --> N(-) If an atom loses an electron, it becomes a cation and positively charged. Cations are smaller than the original atom because of the lost electrons. N(2+) = cation
What is the charge of an element if it loses an electron?
It depends on the charge on the atom at the start before it gains an electron. The electron has a charge of -1, and will make an atom more negative or less positive (both of which are the same thing). Let's look at the possibilities. If an atom is neutral (zero net charge) and gains an electron, it has a net charge of -1. If an atom is at +1 and gains an electron, it has a net charge of zero. If an atom has any positive charge, p, above +1, it has a net charge of p - 1. (A +5 would become a +4, and a +3 would become a +2.) If an atom has any negative charge, n, then its net charge becomes n - 1. (A -4 would become a -5, and a -2 would become a -3.)
How many electron shells does the largest atom have?
The largest atom is calcium which has 4 shells.
To which series would the emitted light belong if an electron in a hydrogen atom underwent a transition from level n 5 to level n 1?
The electron transition from n=5 to n=1 in a hydrogen atom corresponds to the Balmer series, specifically the Balmer-alpha line which is in the visible part of the spectrum.
Define main energy levels and quantum numbers?
Main energy levels are designated by integers (n=1,2,3,...) and represent the overall energy of an electron in an atom. Quantum numbers (n, l, m, s) describe the specific properties of electrons, such as energy level (n), orbital shape (l), orientation in space (m), and spin (s). Each electron in an atom has a unique set of quantum numbers that determines its behavior within the atom.
When an atom loses or gains an electron?
If an atom gains an electron, it becomes an anion, which is negative. Anions are larger than the original atom because of the added electrons. N + electron(-) --> N(-) If an atom loses an electron, it becomes a cation and positively charged. Cations are smaller than the original atom because of the lost electrons. N(2+) = cation

What happens when an atom loses or gains electrons?
it becomes a charged ion loose = positive gain= negative
When an atom loses an electron and becomes negatively charged we refer to it as an?
Positive ion. Examples: H+ Na+ Li+ Be+ N+ Lost multiple electrons? H2+ Na2+ Li3+ H5+
When one atom loses an electron and another accepts that electron?
It depends on the exact situation. Probably ions Well this answer is vaguely correct. When an atom gains or loses an electron it becomes an ion. Ions with a net positive charge are called cations and ions with a net negative charge are anions. This allows for an ionic bond to occur. An ionic bond occurs when an anion binds with a cation.
What is the symbol for each of the 3 parts of an atom?
e- = electron p+ = proton N = neutron

How many electron in an atom?
n=4 s=-1/2 n=3 l=0
How much energy is released by the atom when an electron moves from n 3 to n 2?
182 kJ
In many-electron atoms which quantum numbers specify the energy of an electron?
the quantum number n determines the energy of an electron in a hyrdogen atom.
What quantum number of the hydrogen atom comes closest to giving a 31--diameter electron orbit?
The quantum number that determines the size of an electron's orbit in a hydrogen atom is the principal quantum number, denoted by "n." For an electron orbit with a 31 Å diameter, the closest principal quantum number would be n = 4, because the average radius of the electron for an orbit corresponding to n is approximately given by n^2 Å in hydrogen atom.
