Which one of the following is not isoelectronic with Kr a. As3 plus b. Se2- c. Rb plus d. Sr2 plus e. Br-?
c. Rb plus. Kr has 36 electrons, the same as Se2-, As3+, Sr2+, and Br-. Rb plus has 35 electrons, which is not isoelectronic with Kr.
What - 2 ion is isoelectronic to Na plus?
Mg^2+ is isoelectronic to Na^+ because it has the same number of electrons (10) as Na^+ after losing two electrons to achieve a stable octet configuration.
Why is argon isoelectronic with Ti4 plus?
Argon has 18 electrons, while Ti4+ has 22 electrons. When Ti loses 4 electrons to form Ti4+, it loses the outer 4s2 and 3d2 electrons, leaving an electron configuration of [Ar] for both species, making them isoelectronic.
What is isoelectronic with Al3 plus?
10
What is the chemical formula for Fe 3 plus and Br-?
Iron ions, Fe+3, will bind to oxygen ions, O-2, in a ratio that depends on their charges since the total positive charges in the molecule must equal the total negative charges. The eventual number of positive and negative charges is found by the least common multiple of the charges. In this instance, the charges are 3 and 2. The least common multiple is 6, so two atoms of the Fe+3 are needed to have a total positivie charge of +6, and three O-2 are needed to have a total negative charge of -6 to provide the electrical balance. The resulting molecule is Fe2O3.

Why plus and minus symbols are used to specify the electron charges?
The plus and minus symbols are used to represent positive and negative charges, respectively. In the case of electrons, the minus sign indicates that electrons have a negative charge. This convention helps distinguish between different types of charges in physics and chemistry.
S2- Cl1- K1 plus and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
What does an electron plus electron equal?
An electron plus an electron will repel each other due to their negative charges. This is because like charges repel each other according to the principles of electromagnetism.
Is Zn 2 plus and Cu2 plus a isoelectronic specie?
Yes, Zn²⁺ and Cu²⁺ are isoelectronic species. Both ions have the same number of electrons, with Zn²⁺ having 30 electrons (atomic number 30, losing 2 electrons) and Cu²⁺ having 29 electrons (atomic number 29, losing 2 electrons). As a result, they both have the electron configuration of [Ar] 3d¹⁰, making them isoelectronic.
S2- Cl1- and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
What is the overall charge of the atom since the atom contains positive charges and negative charges. how is that possible?
An atom is always neutral of charge, meaning ZERO. This is possible because of the equal numbers of (positive) protons and (negative) electrons, each plus charge is compensated by one (equally negative) minus charge.
Negative plus negative equals what?
A negative plus a negative equals a negative.
Does a negative plus a negative equal a postive?
No, a negative plus a negative is a negative
