This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
Phosphorus (P) has 15 electrons.
A fluorine atom has 9 electrons.
Aluminum has three unpaired electrons.
When an object has too many electrons, it carries a negative charge. This is because electrons have a negative charge, so an excess of electrons on an object results in an overall negative charge.
There are 6 2p electrons in argon.
Strontium (Sr) has an atomic number of 38, meaning it has 38 electrons in its neutral state. When it loses two electrons to become Sr²⁺, it has 36 electrons remaining. Therefore, Sr²⁺ has 36 electrons.

There are two outer electrons in strontium (Sr) since it belongs to Group 2 of the periodic table. Group 2 elements have 2 electrons in their outer energy level.
Sr has two electrons in the highest occupied energy level
The Lewis dot structure for strontium (Sr) shows it with two valence electrons, represented as Sr: ••. For selenium (Se), which has six valence electrons, the structure would be Se: •• •• ••. When forming a compound, strontium donates its two electrons to selenium, resulting in the formation of strontium selenide (SrSe), where Sr becomes a cation (Sr²⁺) and Se becomes an anion (Se²⁻). The resulting ionic bond reflects the transfer of electrons from Sr to Se.
Examples: Ca, Mg, Ba, Sr, Ra, etc.
The strontium ion is Sr2+ with the same electron configuration as Kr. Sr element has an atomic number of 38- the neutrl Sr tom has 38 protons in its nucleus and 38 electrons - therefore the ion Sr2+ has 2 less - 36.
Strontium ion has 0 electrons in its outer shell because it has lost two electrons to become stable. In its neutral state, strontium (Sr) has 2 electrons in its outer shell.
Strontium (Sr) typically loses two electrons to achieve a stable electron configuration. This occurs because strontium is an alkaline earth metal located in Group 2 of the periodic table, and it readily forms a +2 cation (Sr²⁺) by losing its two outermost electrons. Therefore, strontium loses two electrons during chemical reactions.
The element with 38 electrons is Strontium (Sr). Strontium is an Alkaline Earth Metal in Period 5 of the Periodic Table. Strontium has 38 electrons, 5 electron shells and 2 electrons in the outer shell.
Strontium (Sr) has an atomic number of 38, meaning it has 38 protons. The most common isotope of strontium is Sr-88, which has 50 neutrons (88 total nucleons minus 38 protons). The Sr²⁺ ion indicates that it has lost two electrons, but the number of neutrons remains unchanged, so Sr²⁺ still has 50 neutrons.
Yes, Sr(NO3)2 is an ionic compound. Strontium (Sr) is a metal and nitrate (NO3) is a polyatomic ion. When they combine, the Sr atom loses electrons to become a cation and the NO3 ion gains electrons to become an anion, resulting in an ionic bond between them.
