True
No, hydrochloric acid contains hyrogen and chlorine, so therefore it is not an element.
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
Element number 13 in the periodic table of elements is aluminum. Element 13 is also the name of a rock band.in Milwaukee Wisconson that has been around about four years.
In alpha decay, the nucleus loses two protons and two neutrons. The resulting element will therefore have an element number that is two less.In beta minus decay, a neutron gets converted to a proton. The resulting element will have one more proton - the element number will be one more. In beta plus decay, a proton gets converted to a neutron. The resulting element will have one less proton - the element number will be one less.
The number and arrangement of electrons in atoms of an element determine the chemical properties of the element.
This chemical element is calcium (Ca).
Chlorine
No element has the exact same election arrangement as another element. However ion can have the same election arrangement as another element. For example Chloride (Cl-) has the same configuration as Argon, and Potassium (I) (K+) also has the same configuration as argon.
The number and arrangement of electrons.
Chlorine
There is a sea of delocalised electrons formed in a metallic element, and the ions are attrracted to this.
smallest particle of an element that retains the properties of that element.
by using index position we can find the particular element in array.
allotrope
PCl5 is phosphorous pentachloride. Which is in a trigonal bipyramidal arrangement.
element, specifically an alkali earth metal.
