An element with a 3- charge in the 4th energy would have a strong, stable nucleus with a strong nuclear force holding the protons and neutrons together. This element would also have a strong, repulsive electrostatic force between the protons in the nucleus and the electrons in the 4th energy level.
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
the cyanide ion has a single negative charge, CN-
The element with 15 protons and 16 neutrons is phosphorus (atomic number 15). The net charge of negative 3 means it has gained 3 electrons, making it an ion of phosphorus with a charge of -3.
The element in period 3 with 8 electrons in its outermost energy level is chlorine (Cl).
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 charge is 3+
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
the charge is 3+
the cyanide ion has a single negative charge, CN-
Any particle with 24 protons, despite the number of neutrons or the charge, is chromium.
The element is likely lithium (Li). Lithium has 3 electron energy levels (shells) and 3 valence electrons in its outermost energy level.
The element is vanadium (V) because it has 23 protons. With 18 electrons and a net charge of 3 plus, it would have lost 3 electrons, resulting in a net charge of +3. The number of neutrons (28) does not affect the charge or identity of the element.
The element with 15 protons and 16 neutrons is phosphorus (atomic number 15). The net charge of negative 3 means it has gained 3 electrons, making it an ion of phosphorus with a charge of -3.
The element in period 3 with 8 electrons in its outermost energy level is chlorine (Cl).
Indium is a metallic Element ... at. wt. 114.76, at. nu. 49, with valence of 3,2,1. It is normally found in Zinc Blends, in sphalerite ore and, is a soft, white metal with a bluish tinge ... ductile, malleable and will leave a make on paper. It is stable in air.
Are you referring to P, phosphorous?
A cation is any element with a positive charge. Lead most commonly forms an anion, which means it has a negative charge. But any element can have any charge, but only under certain condistions
