What subatomic particles determine the chemical properties?
The chemical properties of an element are determined by the subatomic particle known as a proton.
What are the 3 subatomic particles of an atom and describe them?
There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don’t have a charge.
What is the atomic number of an element with 12 protons 10 neutrons and 12 electrons?
What is the atomic number of an element with 12 protons 10 neutrons and 12 electrons. 12 protons, 12 neutrons, 10 electrons This is a magnesium ion.
When determining an elements chemical properties the most important subatomic particles to analyze are?
protons
Explanation: Since Z is EXPLICITLY determined by the number of protons, massive, positively charged particles, present in the element’s nucleus, the proton must be the greatest determinant. Of course, it is the electrons that actually do the chemistry, but Z defines the element.
Why isotopes of an element have the same chemical properties?
Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
What is the chemical symbol for the ion with 12 protons and 10 electrons?
Symbol: Mg2+ The symbol of the ion having 12 protons and 10 electrons is Mg2+.
How are elements arranged on the periodic table?
In the modern periodic table, the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom. In a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group).
How do you rank the three subatomic particles in order of mass?
Rank the three subatomic particles in order of increasing mass: (a) neutron, (b) proton, (c) electron. The element bromine, Br (atomic number 35), has two major isotopes of similar abundance, both around 50%. The atomic mass of bromine is reported in the periodic table as 79.904 amu.
Is it possible to discuss the chemical principles of subatomic particles?
Although this is an oversimplification that ignores the other subatomic particles that have been discovered, it is sufficient for discussion of chemical principles. Some properties of these subatomic particles are summarized in Table 1.8.1, which illustrates three important points:
What is the atomic shape of magnesium on the periodic table?
Magnesium – Periodic Table – Atomic Properties. Magnesium is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure.
What is the relationship between protons and neutrons in an atom?
The number of neutrons in the nucleus equals the number of protons. C. The protons and neutrons together comprise most of the mass of the atom D. The electrons comprise the nucleus of the atom E. The number of protons equals the number of electrons in the neutral atoms A,C,D
