Answer:
one potassium, one nitrogen and three oxygen
Explanation:
potassium is K, nitrogen is N and oxygen is O
Answer:
The answer to your question is: 45 electrons
Explanation:
Isotopes are molecules that have the same number of protons but the number of neutrons is different.
Also, in a neutral atom, the number of protons and electrons is the same.
In the example given, we can see that the atom is neutral so, the number of protons = 45 and the number of electrons = 45.
Answer:
Phosphorus makes 5 bonds with other atoms
Explanation:
has total 32 number of valence electrons (P has 5 , O has 6 and Cl has 7 valence electrons).
These valence electrons are used to draw Lewis structure of .
Formal charge on an atom = (no. of valence electrons of the atom)-(no. of covalent bonds attached to the atom)-(no. of electrons in lone pair of the atom)
Applying octet rule (atoms have eight electrons in their valence shell) and minimizing formal charge of , it has been found that P makes total 5 bonds with rest of the atoms.
Lewis structure of along with formal charge (in parentheses) has been given below.
