The atomic number of nitrogen is 7. How many protons, neutrons, and electrons make up an atom of nitrogen-15?
1 Answer
Nitrogen is atomic number 7, which means each nitrogen atom has 7 protons. Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas. Nitrogen atom, juga dikenal sebagai nitrogen aktif, sangat reaktif, berbentuk triradikal dengan tiga elektron yang tidak berpasangan.
By definition, if
Explanation:
The nitrogen atom features a lone electron pair that can bind H + to form an ammonium ion R 3 NH +. The lone electron pair is represented in this article by a two dots above or next to the N. The water solubility of simple amines is enhanced by hydrogen bonding involving these lone electron pairs. The configuration notation for Nitrogen (N) provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of the Nitrogen atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.
Nitrogen Atom Configuration
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have
