How many electrons are in a +3 cation with an atomic number of 13?

Here, mass number is 27 and there are 14 neutrons hence protons=27-14=13. In a neutral atom, number of protons=number of electrons. Hence in this case the number of electrons in the neutral atom will be 13. Now, since the atom carries +3 charge hence it will have 13-3=10 electrons.
A.

How many protons and neutrons are in aluminum 27?

A quick looks in the periodic table will show that aluminium has an atomic number equal to 13 . This means that any atom that is an isotope of aluminium will have 13 protons in its nucleus.
  • What is the number of neutrons in aluminum?

    The number of neutrons in an aluminum atom depends on the isotope. Al has the atomic number 13, that is it has 13 protons in the atom (Aluminium ). The most common and natural isotopes are Al27 and Al26 thus these atoms have 14 and 13 neutrons respectively (Isotopes of aluminium ).
  • How many electrons are in aluminum?

    13 electrons
  • How many neutrons are in a neon atom?

    Elements are defined by the number of protons they have. If the atom is neutral, uncharged, it will have 10 electrons. There are three naturally occurring isotopes of neon, neon-20 with 10 neutrons, , neon-21 with 11 neutrons, and neon-22 with 12 neutrons.

  • Is aluminum a solid or a liquid?

    British editors amended the name again to aluminium which is the modern preferred British form, to better harmonize with other element names like sodium, potassium, etc. Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid.
  • How many protons and neutrons are in an atom of Al 27?

    A quick looks in the periodic table will show that aluminium has an atomic number equal to 13 . This means that any atom that is an isotope of aluminium will have 13 protons in its nucleus.
  • What is the family that aluminum is in?

    Group 13: The Boron Family. The boron family contains elements in group 13 of the periodic talbe and include the semi-metal boron (B) and the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
C.

How many orbitals does aluminum have?

So for the element of ALUMINUM, you already know that the atomic number tells you the number of electrons. That means there are 13 electrons in a aluminum atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and three in shell three.
  • What is used to make aluminum?

    Aluminum compounds occur in all types of clay, but the ore that is most useful for producing pure aluminum is bauxite. Bauxite consists of 45-60% aluminum oxide, along with various impurities such as sand, iron, and other metals.
  • How did Aluminum get it's name?

    Aluminum gets its name from the mineral alum, which gets its name from the Latin word "alumen" meaning "bitter salt." There are a number of aluminum isotopes, but only two occur naturally: aluminum-27 (stable) and aluminum-26 (radioactive).
  • What is the color of aluminum?

    Data Zone
    Classification:Aluminum is an 'other metal'
    Color:silvery
    Atomic weight:26.98154 g/mol
    State:solid
    Melting point:660.32 oC, 933.57 K
