How many electrons does the neutral atom gain or lose when Cr3 plus forms?
When Cr3+ forms, the neutral atom (chromium) loses 3 electrons. This happens because the neutral chromium atom has 24 electrons, but when it forms Cr3+, it loses 3 electrons to have a total of 21 electrons.
What is the equation for a chromiumIII ion from a neutral chromium atom?
A chromium atom loses three electrons to become a Cr3+ ion. The equation for this process is Cr → Cr3+ + 3e-.
How many electrons are in an Mg2 plus ion?
An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
What bond is chromium and sulfur?
The bond between chromium and sulfur is typically an ionic bond. Chromium tends to lose electrons to form a positive ion, while sulfur tends to gain electrons to form a negative ion, resulting in electrostatic attraction between the two ions.
What do you call an atom that gains or loses electrons?
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.

Electron configuration of chromium II ion?
The electron configuration of a chromium II ion (Cr^2+) is [Ar] 3d^5. Chromium normally has an electron configuration of [Ar] 3d^5 4s^1, but when it loses two electrons to form the Cr^2+ ion, the 4s^1 electron is lost first, resulting in a 3d^5 configuration.
How many protons and electrons in Be2 plus ION?
Beryllium (Be) has 4 protons and 4 electrons in its neutral state. When it forms the Be2+ ion, it loses two electrons, leaving it with 4 protons and 2 electrons. The Be2+ ion has a 2+ charge because it has lost two negatively charged electrons.
How does an atom become a positive ion a nevative ion?
An atom becomes a positive ion by losing electrons, resulting in more protons than electrons. This creates a net positive charge. An atom becomes a negative ion by gaining electrons, leading to more electrons than protons. This creates a net negative charge.
What is the electron configuration of germanium ion?
The electron configuration of germanium ion (Ge2+) is [Ar] 3d10 4s2 4p2. Germanium normally has 32 electrons, but as a 2+ ion, it loses two electrons, resulting in the configuration mentioned.
What is one atom ion called?
A one-atom ion is called a monatomic ion. It is formed when an atom gains or loses electrons, resulting in a net positive or negative charge.
What is the name of a positive ion?
A positive ion is called a cation. It is formed when an atom loses one or more electrons, resulting in a net positive charge.
If an atom loses an electrons what will its resulting charge be?
An atom that loses one or more electrons becomes positively charged, because the number of protons (+) in the nucleus will outnumber the electrons (-).
