Atomic Number: The atomic number of an element represents the number of electrons or the number of protons in the element while the atomic mass represents the sum of neutrons and protons that exist in the element. Answer and Explanation:
If the atomic number of an element is 12 and the atomic mass is 25: a. How many protons are there in the nucleus? b. How many neutrons are there in the nucleus? c. How many electrons are in the atom? How many electrons are ...
Accessing an object property with a dynamically-computed name (22 answers) Closed 4 months ago. I have an object and I can reference key a as in the following: var obj = { a: "A", b: "B", c: "C" } console.log(obj.a); // return string : A I want to g...
An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. The nucleus consists of positively charged protons and neutrally charged neutrons. The number of protons in the nucleus defines the atomic number of an element, and the number of electrons in a neutral at...
five electrons, the net charge of the element is +1. Conversely, if an element has six protons but seven electrons, then the net charge of the element is -1. In reality, all elements are neutral in their natural state, and it is the gain or loss of electrons that determines their ...
Atoms are characterized by their tiny size (about 1 x 10^-10 m across) and their inclusion of protons, electrons and (except in the case of hydrogen) neutrons. Atomic radii are a function of both atomic number and element period, with radii increasing fr
The atomic number is the number of protons an element has. The atomic number increases by one as we move one element to the right. That is to say, if an element has an atomic number of 25, the element directly on its right will have the atomic number 26. When we reach the end of...
MALE PROFESSOR: And it's arranged according to increasing atomic number, which is … ? FEMALE STUDENT: The number of protons in each atom of an element. MALE PROFESSOR: Right.Well, early versions of the periodic table had gaps. Missing elements.Every time you have one more proton you have...
Artwork: Isotopes are atoms of an element that contain the same number of protons and electrons but different numbers of neutrons. An unstable (radioactive) isotope will naturally try to make itself more stable by getting rid of some of these particles and changing into a different atom....
