16 neutrons
How many protons does P 3?
15 protons
Is SI a neutral atom?
The element Silicon (Si), is in group 14/IVA on the periodic table. A neutral silicon atom has equal numbers of protons and electrons. The number of protons is its atomic number, which is 14. So the number of electrons is 14.
What element has 15 protons 15 neutrons and 15 electrons?
Name Phosphorus
What isotope has 14 protons and 15 neutrons?
Silicon-29
What isotope has 13 protons and 15 neutrons?
Aluminum
What element has 18 protons and 18 neutrons?
Name Argon
What is the number of protons for aluminum?
13
What is the number of electrons for aluminum?
thirteen
What kind of charge is predicted to form by aluminum?
3+
What will be the charge on aluminum when it fulfills the octet rule?
+3 because all Group 13 ions will lose 3 electrons (this is easier than gaining 5 electrons!) to fulfill the Octet Rule. For example Aluminum’s ion possesses 13 protons and 10 electrons- it’s overall charge is +3.
What are the octet rule exceptions?
However, there are three general exceptions to the octet rule: Molecules, such as NO, with an odd number of electrons; Molecules in which one or more atoms possess more than eight electrons, such as SF6; and. Molecules such as BCl3, in which one or more atoms possess less than eight electrons.
Which period can expand octet?
An element from Period 3 and below will be able to expand octet by making use of its energetically accessible, or low lying d-subshell for bonding. This means only Period 2 elements such as C, N, O and F cannot expand octet and have to obey octet rule.
What is expanded octet rule?
Main group elements that form more bonds than would be predicted by the octet rule are called hypervalent compounds, and have what is known as an ‘expanded octet,’ meaning that there are more than eight electrons around one atom.
