What elements has four valence electrons shows properties of metals and nonmetals and has 14 protons in the nucleus of each atom?
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.
What else can I help you with?
Where are protons and electrons that are responsible for the chemical properties of an atom are located?
Protons are located in the nucleus of an atom, while electrons are found in the electron cloud surrounding the nucleus. The number and arrangement of protons and electrons determine the chemical properties of an atom.
Why elements share similar characteristics?
Elements share similar characteristics because they have the same number of electrons in their outermost energy level, which determines their chemical properties. This similarity is due to their placement in the periodic table, where elements in the same group have the same number of valence electrons. These shared characteristics allow elements to react in similar ways and form similar types of compounds.
Which electrons account for many of the chemical and physical properties of elements?
Valence electrons are the electrons that account for many of the chemical and physical properties of elements. These are the electrons in the outermost energy level of an atom and are involved in chemical bonding and reactions. The number of valence electrons determines an element's reactivity and ability to form compounds.
What determines an elements property?
Chemical properties of an element determine by the number of electron
Describe the basic particle from which all elements are made?
The basic particle from which all elements are made is an atom. Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons. Different elements are characterized by the number of protons in the nucleus, which determines their unique chemical properties.
Which properties of the elements are related to the attraction between the nucleus and electrons in atoms?
These are the chemical properties.
Where are protons and electrons that are responsible for the chemical properties of an atom are located?
Protons are located in the nucleus of an atom, while electrons are found in the electron cloud surrounding the nucleus. The number and arrangement of protons and electrons determine the chemical properties of an atom.
Outside the nucleus are electrons that are involved in what?
Outside the nucleus, electrons are present in their orbits. The valence electrons present outside is involved in forming bonds with other atoms. (figure it out yourself scrub)

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.
What do all elements from the periodic table have in common?
Nucleus in the centre (with protons and neutrons) with the electrons revolving around it.
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
What determines an elements property?
Chemical properties of an element determine by the number of electron
Why do different elements have different properties?
Different elements have different properties because of the arrangement of electrons in their atoms. The number of protons in the nucleus determines the element's identity, while the arrangement of electrons determines its properties. Factors like atomic structure, electron configuration, and bonding behavior contribute to the unique characteristics of each element.
How Are Elements Laid Out On The Periodic Table?
Scientists organize the elements on the periodic table by chemical properties and also according to their energy levels. They can also be laid out by groups, valence electrons and periods.They are also classified as metals, nonmetals, metalloids, and noble gases.
What determines an elements chemical properties?
An element's chemical properties are determined primarily by its electron configuration, which influences how it will react with other elements to form compounds. The number of protons in the atom's nucleus also plays a role in determining its chemical properties. Additionally, factors such as atomic size, electronegativity, and valence electrons contribute to how an element will interact chemically with other elements.
