Ato A new substance has been found with 73 protons and an atomic mass of 192. The name of the element with atomic number 7. The number of protons and neutrons in the nucleus of an atom. Nitrogen is a p-block element and its symbol is āNā. The number of protons in the nucleus of an atom. Therefore, the atomic number of nitrogen (N) is 7. Write the distribution of electrons in an atom of element whose atomic number is 18. The nitrogen atom contains a total of seven electrons and protons.What would be the (a) atomic number, (b) mass number, (c) the number of electrons, and (d) the number of valence electrons, per atom of this element? The nucleus of an atom has 5 protons and 6 neutrons. Name: Nitrogen Atomic Number: 7 Element Symbol: N Group: 15 Period: 2 Block: p Element Family: nonmetal Atomic Mass: 14.006 43 14.007 28 IUPAC guidelines.The electrons present in the outermost shell are called(a) valency electrons (b) octate electrons(c) duplet electrons (d) valence electron.The number of valence electrons in a graphite atom is :(a) 2 (b) 4 (c) 3 (d) 5 The nitrogen atom has 2 electrons in its first shell and 5 electrons in its second electron shell (outermost shell of nitrogen atom).(a) What are valence electrons? Where are valence electrons situated in an atom?(b) What is the number of valence electrons in the atoms of an element having atomic number 13? Name the valence shell of this atom. Number of electrons in nitrogen 7 Electronic configuration of nitrogen From the above configuration, the valence electrons in nitrogen is 5 because the last.having electronic configuration 122 2 2 s2,s2px1 p1y p z1 is 7 and nitrogen has atomic number 7. The mass number is a sum of protons and neutrons. Based on the periodic table Nitrogen has a mass number of 14. Find the number of valence electrons in it. 3d5 Therefore, number of unpaired electrons 5. This means that we will have 7 electrons. hold up to 10 electrons, and the f subshell has 7 orbitals with 14 electrons.
