All elements in column 2 of the Periodic Table consistently form ions with a charge of two plus. This column is commonly referred to as the Alkaline Earth Metals. please feel free to send me a trust point if this was helpful =]

What element has 2 electrons and a charge of negative 1?
A negative hydrogen ion.
How does sulfur forms its ion?
ions are formed based upon the valence electrons of the element and if the element is a metal or a nonmetal. S has 6 valence electrons and needs 2 more to be stable. it is a nonmetal. therefore, taking on 2 electrons gives S a -2 charge
What is the symbol for an ion with 16 protons 16 neutrons and 18 electrons?
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
How many eletrons are in oxygen?
An oxygen atom has always 8 electrons (unless it's an ion where it has picked up 2 electrons and carries a -2 charge).In an O2 molecule there are 2*8 = 16 electrons and in an O3 molecule there are 3*8 = 24 electrons.
How many electrons does an ion of beryllium have if it has a -2 charge?
Beryllium is element 4, so the "neutral" atom would have 4 protons and 4 electrons. In order to have a "-2" charge, it would need 6 electrons.
What element has 10 electrons when it form an anion with a 2 negative charge.?
A certain element forms an ion with 10 electrons and a charge of +2. Identify the element
How many protons and electrons in Be2 plus ION?
Be2+ ion has 4 protons and 2 electrons
What element has 2 electrons and a charge of negative 1?
A negative hydrogen ion.
Ca2 plus has how many electrons?
Calcium normally has 20 electrons. Because it has a plus 2 charge, it must have two less electrons. Therefore, the calcium ion has 18 electrons.
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
What element has 2 electrons and 7 protons?
it must be a 5+ ion of element nitrogen and it is very difficult to produce.
What element has 8 protons and 10 electrons?
No neutral element has these characteristics. However, the oxide ion, O-2, does have them.
When this element gains 2 electrons it has the electron configuration of the noble gas Argon?
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
A M2 plus ion derived from a metal in the first transition metal series has four electrons in the 3d subshell What element might M be?
It's chromium. The element would have lost 2 electrons from the 4s subshell, leaving 3d4 as your valence.
What is the charge of the ion with 27 protons and 25 electrons?
An ion of copper, Cu+2, has 27 electrons and a charge of +2. The copper atom has loaned out (or had borrowed from it) in a chemical reaction, those 2 electrons. An ion is formed any time the number of electrons an atom has does not equal the number of protons in its nucleus. The 2 electrons plus 27 electrons makes 29 electrons - just the number that are present in a neutral atom of copper.
Does an element that loses 3 electrons have a charge of plus 2?
If an atom loses 3 electrons, it gets a charge of +3. (One positive charge for every electron lost). If an atom loses 2 electrons, it gets a charge of +2.
When does an atom become an ion with a charge of 2 plus?
Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.
