Why most of the transition metal not displace hydrogen in acid?
because some metals are less reactive than hydrogen.
Is lithium an isotope ion or neutral atom?
Lithium is two of these but at the same time neither. It's an element. It is best described as an element, a type of atom with unique properties. If the number of neutrons varied, the multiple lithium atoms would be called isotopes. As for neutral vs. ion, if the number of protons is equal to the number of electrons, it is neutral. If it is not, it is an ion, specifically anion (less protons) or cation (more protons). It will always be a neutral atom or ion. It will always be an isotope, but only called so when in a group of lithium atoms with various numbers of neutrons.
Are transition metals on the periodic table reactive?
yes, they are less reactive than group 1 and 2. These metals hardly react with air or water at all whereas Group 1 and 2 metals tarnish quickly and react with water
How can cheating agents act as antioxidants?
A cheating agent has a crab-claw-like ligand which coordinates to the metal ion. This decreases the concentration of free transition metals in solution so there is less chance of oxidation. An example of a chelating agent is the rosemaric acid.Chelating agents (such as EDTA) chelates the divalent metal ions such as Mg2+ or Zn2+
How many fewer protons are found in thorium than uranium?
Thorium: 90 protons Uranium: 92 protons
What alkaline earth metal has more protons then argon but less protons then krypton?
This chemical element is calcium (Ca).
What classification is the element nickel belong to?
Nickel belongs in family(or group) 10, transition metals. The elements in this group are Nickel, Palladium, Platinum, and Ununnilium, in order of increasing atomic mass. A link is provided.
Would a metal in Group 13 be more or less reactive that a metal in Group 1?
less reactive.beacuse group-1 elements are the most reactive elements.
Which group in the periodic table is less reactive?
Group 7 in the periodic table is less reactive.They are Manganese,Technetium,Rhenium and Bohrium.They all are transition metals.
Why most of the transition metal not displace hydrogen in acid?
because some metals are less reactive than hydrogen.
How do transition metals properties compare with those of elements farther to the left?
The chemical reactivity of transition metals is generally less than that of metals to its left (group 1 and group 2 metals). However, transition metals can exhibit various oxidation states and hence form more number of compounds than group 1 and group 2 elements.
Is it true that transition metals are less reactive than the metals in group one and two of the periodic table?
True
A metal containing 3 valence electrons and 13 protons in its atom is what metal?
The fact that the element has 13 protons indicates that this element is aluminum. The number of protons in the nucleus is the atomic number of an element. Every element has its own unique atomic number that never changes in ordinary chemical or physical reactions.
Would a metal in group 13 be more or less reactive than a metal in a group 1?
The metals in group 13 would be less reactive than the metals in group 1 because the metals in group 1 are closest to the left of the Periodic Table. And any thing to the left are more reactive.
What element has more than 50 but less than 75 protons and is in group 17?
Any one element can ONLY have a single fixed number of protons. Th only element with a number of protons that sits between 50 and 75 in group 17 of the periodic table is Iodine (I), with 53 protons.

What kind of elements has less than 4 valence electrons?
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons
