Strontium
A strontium ion has a charge of +2
The strontium ion is called the Sr2+ ion. It has a 2+ charge due to the loss of two electrons from a neutral strontium atom.
Boron gains noble gas configuration by losing 3 electrons. So it forms positive ions.
An atom of strontium becomes a strontium ion with a +2 charge by losing two of its outermost electrons. Strontium, which is in Group 2 of the periodic table, has two electrons in its valence shell. When it loses these two electrons, it achieves a stable electron configuration similar to that of noble gases, resulting in a positively charged ion (Sr²⁺). This process is driven by the atom's tendency to attain a lower energy state and increased stability.
This question is quite hard to understand. If you want the full words it's strontium plus. However, the metal strontium is in group II and usually forms Sr 2+. If you want the full electronic configuration it is 2,8,18,8,1 for the unipositive ion and 2,8,18,8 for the dipositive ion. To show this with the full subshell notation is very confusing without being able to do superscripts, but it's the same as krypton for Sr 2+, and [Kr] 5s1 for Sr +.
Strontium.
strontium is a metal, therefore it must form only positive ions.
A strontium ion has a charge of +2
A strontium ion has a charge of +2
Boron typically forms a 3+ ion, called boron (III), by losing three valence electrons.
Strontium can be a neutral atom or a cation.
boron ion is represented as B+, singly charged, positive.
The ion charge of a boron atom can vary depending on the specific ion formed. Boron typically forms ions with a charge of +3 by losing three electrons to achieve a stable electron configuration.
Boron typically forms positive ions (cations) in chemical compounds. One common boron ion is the boron cation, B3+.
The strontium ion is called the Sr2+ ion. It has a 2+ charge due to the loss of two electrons from a neutral strontium atom.
Boron forms a tri-positive ion.
This just means it has a charge of 1+. The Boron ion can only have a charge of 1+.
