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.
Ion Sr2+ has 38 protons and 36 electrons. The number of protons remains the same as the atomic number of the element (38). The ion has a 2+ charge, indicating a loss of 2 electrons from the neutral Sr atom.
By definition, every atom of every element must have the same number of protons as every atom of that same element. So, all you have to do is find which element has 35 protons. Look at the periodic table, and find the 35th listed element. That element is Bromine. So Bromine is the correct answer.
The element with 18 protons is argon (Ar), with atomic number 18. Its mass number is calculated by adding the protons and neutrons, so 18 protons + 20 neutrons = mass number 38 for this particular isotope of argon.
When it comes to zinc, the amount of neutrons is considerably higher than the number of protons and electrons. In zinc there are 30 protons include, 35 neutrons and 30 electrons. Unless you are dealing with Ion, the number of protons is always equal to the number of electrons.
I think you meant "54 protons, 54 electrons, and 78 neutrons," because I don't think it's possible for any element to have such a high proton-electron different, especially when that element is the noble gas Xenon. Anyways, if you did make a typo, the element you're thinking of should be Xenon-134
Ion Sr2+ has 38 protons and 36 electrons. The number of protons remains the same as the atomic number of the element (38). The ion has a 2+ charge, indicating a loss of 2 electrons from the neutral Sr atom.
The atom with 38 protons, 50 neutrons, and 36 electrons is Strontium (Sr), as the number of protons determines the element. It belongs to the alkali earth metal group and is commonly used in fireworks and flares to produce a bright red color.
Strontium's atomic number is 38. So, it has 38 protons and 38 electrons if it's neutral. Strontium is a group 2 element and so has 2 valence electrons. Thus, the rest of the 36 electrons are core electrons.
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 has several natural isotopes, and many artificial ones. Taking Sr84 as the one to study, it has 38 protons, 38 electrons, and 46 Neutrons.
By definition, every atom of every element must have the same number of protons as every atom of that same element. So, all you have to do is find which element has 35 protons. Look at the periodic table, and find the 35th listed element. That element is Bromine. So Bromine is the correct answer.
The number of protons is 30, the number of electrons is 28, the number of neutrons is different for each isotope.
Strontium is an element (38Sr) in period 5 with 38 protons, and being neutral it has 38 electrons also.However, also 37Rb- ion would have 38 electrons, but with only 37 protons in period 5.
The element with 18 protons is argon (Ar), with atomic number 18. Its mass number is calculated by adding the protons and neutrons, so 18 protons + 20 neutrons = mass number 38 for this particular isotope of argon.
All atoms of the specified data contain 38 protons, 38 electrons (assuming they are not ions), and 50 neutrons. They are atoms of the element Strontium.
38 protons. If it is neutral, it will also have 38 electrons. The number of neutrons obviously varies, depending on the isotope.
You can tell how many protons an element has from its atomic number. So the atomic number of Strontium is 38..so it has 38 protons.
