Consider the student work below.
Did this student correctly interpret the periodic table square? Explain your reasoning in a complete sentence.

A student prepared the diagram below to model atoms of two elements
Atoms of which two elements are represented by these models?
Oxygen, O, and Neon, Ne
Fluorine, F, and Neon, Ne
Silicon, Si, and Phosphorus, P
Beryllium, Be and Boron, B
Which statement accurately describes the atoms of a specific element?
An indium, In, atom contains 115 protons inside the nucleus and 49 neutrons outside the nucleus.
A scandium, Sc, atom contains 45 electrons outside the nucleus and 21 neutrons inside the nucleus
An aluminum, Al, atom contains 27 electrons and 27 protons inside the nucleus.
A zinc, Zn, atom contains 30 protons inside the nucleus and 30 electrons outside the nucleus
Which statement correctly describes the location and charge of the electrons in an atom?
The electrons are inside the nucleus and have no charge
The electrons are outside the nucleus and have a negative charge
The electrons are outside the nucleus and have no charge
The electrons are inside the nucleus and have a negative charge
Using the model of an atom below, what is the charge of the nucleus?
Neutral, there is no charge because the particles cancel each other out
+1
+3
+7
In the early 1900s many scientists thought that an atom consisted of a positive substance with negative charges scattered throughout the substance. Then Ernest Rutherford made a discovery that led to the understanding that an atom consists mostly of empty space with-
Protons orbiting a dense nucleus made of electrons and neutron
Neutrons and protons orbiting a cloud of electrons
Electrons and protons orbiting a cloud of neutrons
Electrons orbiting a dense nucleus made of protons and neutrons
