To figure out which element it is, look at the protons. The number of protons are the atomic number, which you can find on the periodic table. In this case, 8 protons is Oxygen. You also know that it's negatively charged, because there are more electrons than protons. Because there are 2 more electrons, it would have a charge of -2.
Protons and electrons have mass and charge.
there are 19 protons and electrons
The corresponding element is phosphorus.
The number of electrons should = the number of protons.
The N atom is electrically neutral - the number of positively charged protons is equal to the number of negatively charged electrons. That is why there is no net charge on the atom. On the other hand the N3- anion (negatively charged ion) carries a charge of minus 3. It has gain 3 electrons, thereby incurring 3 negative charges. There are 3 more electrons than protons in N3-. N3- can combine with a cation to form an ionic compound.
N3- has 10 electrons and all of those are paired.
2 core electrons and 8 valence electrons are there in N3- ion.
To figure out which element it is, look at the protons. The number of protons are the atomic number, which you can find on the periodic table. In this case, 8 protons is Oxygen. You also know that it's negatively charged, because there are more electrons than protons. Because there are 2 more electrons, it would have a charge of -2.
The protons have a positive charge and the electrons have a negative charge, so it would be 7 + -5, so the charge is +2.
Silicon
15 electrons and 15 protons
Protons and electrons have mass and charge.
Protons do not contain electrons. Protons are positively charged, electrons negatively charged.
35 protons, 36 electrons
N3- and O2- are isoelectronic meaning they have the same exact electron configuration. O2- has one more proton than N3- does so it has a stronger attraction for electrons and it causes the radius to be smaller than N3-.
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
