Arsenic is atomic number 33 and has 5 valence electrons.
Method for finding valence electrons: All electrons are arranged in orbital shells. The inner shell can hold up to 2 electrons. The second shell holds up to 8. The third shell holds up to 18 and so on. The outer shell holds the valence electrons. To find out how many there are, count the electrons in the inner shells 2+8+18 = 28, in this case, and subtract them from the 33 electrons that Arsenic has: 33 - 28 = 5 valence electrons.

Which electrons account for many of the chemical and physical properties of elements?
This is rightThe outermost electrons account for many of the physical and chemical properties of elements.
Where are protons and electrons that are responsible for the chemical properties of an atom are located?
The answer is "the electron." "Valance Electron" is a more specific and correct answer.
Why do elements in a group have the same number of valence electrons?
The elements in a group, also called a family, have similar properties, one of which is the same number of valence electrons. This accounts for why the elements in a group have similar properties.
Why elements share similar characteristics?
All the elements have a nucleus. The nucleus contains protons and neutrons. Electrons move around the nucleus.
Why are flourinechlorinebromine and iodine grouped together?
Because they have similar chemical properties. The reason they have similar chemical properties is because they have the same number of valence electrons. The differences are caused by them having different masses and because the larger elements have their valence electrons "screened" more from the nucleus by electrons in lower energy levels.
Which properties of the elements are related to the attraction between the nucleus and electrons in atoms?
These are the chemical properties.

Which subatomic particle determines the properties of an element?
The number of protons in the atomic nucleus determines the properties of an element. Every element has its own unique number of protons, called its atomic number, which is displayed on the periodic table. The elements are arranged in order of increasing atomic number on the periodic table.
Why elements share similar characteristics?
All the elements have a nucleus. The nucleus contains protons and neutrons. Electrons move around the nucleus.
Buzzing around the outside of a nucleus is called?
If you are talking about elements, they are electrons.

The differences are caused by them having different masses and because the larger elements have their valence electrons "screened" more from the nucleus by electrons in lower energy levels.
Is radioactive acidic?
No, radioactivity is a property of the nucleus. Acid/base properties depend on the electrons orbiting the nucleus.
Why do element in the third period have lower ionization energies than elements in the second period?
With each additional period, there is an additional energy level, which means that the outermost electrons are farther away from the nucleus of the atom. This means that the attractive force of the positively charged nucleus is less, so it takes less energy to remove an electron from an atom in the third energy level than it does from an atom in the second energy level. Therefore, the elements in the third period have lower ionization energies than elements in the second period.
