Usually these elements have a single valency. Those in group 1 form singly charged cations while those in group 2 form doubly charged cations.
It should be:# of protons - # of electronsIt gives you the ion charge of the element. For example, Oxygen ion has 8 protons and 10 electrons. Therefore, 8 - 10 = -2 ----> O2-
No element contains more than one element.
When "x" valence electrons are lost the charge is +x When "x" valence electrons are gained the charge is -x for example, if chlorine gained one electron, the charge would be Cl 1- or, if magnesium lost two electrons, the charge would be Mg 2+
Many of the planets have more than one element. Two of these planets that have more than one element are Earth and Jupiter.
Electrons have a negative charge. When an element had more electrons than protons, it tends to have a negative charge.
Compound made of ions, which are atoms of an element with more or less electrons than number of protons, giving them a positive or negative charge.
I would expect Carbon to be the element that forms more compounds than any other element.
An element with more valence electrons than kernel electrons is typically found in higher energy levels of the periodic table. Examples include elements in the p-block and higher energy levels of d-block, such as sulfur and chlorine. These elements have more valence electrons in their outermost shell compared to the number of electrons in the inner shells.
S-block elements are highly reactive due to the presence of one or two electrons in their outermost electron shell. These elements readily donate or lose these electrons to achieve a stable electron configuration, resulting in strong reactivity with other elements. The reactivity of s-block elements generally increases down the group.
Answer A is correct: there are more electrons than protons. However, if a particle is an anion, it is not an atom. Atoms are electrically neutral.
An ion containing more than one element is called a polyatomic ion. These ions are composed of two or more atoms covalently bonded together and carry an overall charge. Examples include sulfate (SO4^2-) and carbonate (CO3^2-).
An ion that has more electrons than protons has a negative charge.
