How many electrons are in a selenium ion?
Selenium typically has 34 electrons in its neutral state. To determine the number of electrons in a selenium ion, you need to know the specific charge of the ion. For example, a selenium ion with a charge of +2 would have 32 electrons, while a selenium ion with a charge of -2 would have 36 electrons.
Does the atomic number changes when an ion is formed?
No, the atomic number remains the same when an ion is formed. The atomic number is determined by the number of protons in an atom, which does not change when an atom becomes an ion by gaining or losing electrons.
When an ion is created the number of these is changed in the atom?
electrons. the atom either gains or looses electrons to become negatively or positively charged. An ion can also be formed by the addition or subtraction of a neutron.
What is the charge on an ion formed by a sodium atom?
The charge on an ion formed by a sodium atom is +1. Sodium readily loses one electron to achieve a stable electron configuration, resulting in a positively charged ion.
When bromine atom gains one electron?
a bromide ion is formed, the ion formed has a -1 charge, and the ion formed is an anion
What specific ion is formed from an atom of selenium?
The ion Se4+ is common.
Is a chlorine atom or chlorine ion bigger?
A sulfur atom is larger than an oxygen atom.
What ion will be formed by a selenium atom when it has a stable set of valence electrons?
Selenium typically forms an ion with a charge of -2 when it gains two electrons to achieve a stable electron configuration. This forms the selenide ion (Se2-).
What is the formula of the ion compound formed by calcium and selenium?
Calcium selenide, CaSe, is formed.
What is the name of the ion formed by a calcium atom?
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
The ion formed by a fluorine atom is called a?
The ion formed by a fluorine atom is called a fluoride ion, which has a charge of -1. It is formed when a fluorine atom gains an electron to achieve a full outer electron shell.
The ion formed by an arsenic atom is?
The ion formed by an arsenic atom is As3- (arsenide ion) when it gains three electrons or As3+ (arsenite ion) when it loses three electrons.
When is An ion is formed when an atom?
An ions is formed when an atom gains or loses electrons.
An ion is formed when am atom?
An ions is formed when an atom gains or loses electrons.
When is an ion is formed?
An ions is formed when an atom gains or loses electrons.
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.
How many chargesin a sulfur ion?
The most common ion formed from a single sulfur atom is a sulfide ion, with a charge of -2.
