Periodic Table

Some animals can reproduce asexually (without a mate) their offspring are therefore clones of themselves.

ex. Sponges reproduce asexually through budding or fragmentation.

Even some higher order animals such as certain lizards are capable of reproducing asexually, this is called parthenogenesis.

hydrogen has only one electron so after you remove that electron you do not have any electrons left to remove so hydrogen doesn't have a 2nd ionization energy.

hydrogen has 1 proton and 1 electron.

ionisation energy order for gr 14 is

c>si>ge>sn<pb

Group 17 elements are reactive because they only need to gain one electron to achieve a stable electron configuration with a full outer shell (octet). This makes them highly reactive as they readily react with other elements to gain that one extra electron and achieve a stable state.

Numerous forms of Periodic Table have been devised from time to time. Some forms emphasise chemical reactions and valence, whereas others stress the electronic configuration of elements. A modern version the so called long form of the periodic tableof the elements, is the most convenient and widely used.

Yes, if you are comparing a specific diamond to a specific amount of platinum and whether or not it is a setting for a stone or just a lump of metal. The value of a diamond depends on the quality of the individual stone which is based on clarity, cut and color. Platinum is the most valuable metal on earth, but it is weighed differently than diamonds. There is also value of the workmanship when talking about platinum such as in the design of the mounting for a ring or other piece of jewelry. On the whole comparing the value of diamonds and platinum is much like comparing apples to oranges.

No, hydrogen gas is not sonorous. Sonorous means producing sound when struck, and since hydrogen gas is a colorless, odorless, and tasteless gas, it does not produce any sound when struck.

Over 99% of the mass of an atom is contained in the nucleus, where protons and neutrons are located. Electrons, which have negligible mass compared to protons and neutrons, occupy the remaining space in the electron cloud surrounding the nucleus.

CaOHCl is a salt formed from the combination of calcium hydroxide (Ca(OH)2) and hydrochloric acid (HCl). It is a basic salt that can undergo hydrolysis in water to form a basic solution due to the presence of the hydroxide ion from calcium hydroxide.

Electronegativity decreases across a period because the effective nuclear charge increases. This causes the attraction between the electrons and the nucleus to become stronger, making it harder for atoms to attract additional electrons and thus reducing electronegativity.

There are three types of orbitals that involve the third energy level. 3s, 3p, 3d. But when only looking at the third period of the periodic table... The 3s pertains to Na and Mg. 3p pertains to Al, Si, P, S, Cl, and Ar. These tables, as you could say, are called Electron Configurations. Therefore, for Argon, Ar, the electron configuration would be 1s22s22p63s23p6 or in shorter version: [Ne] 3s23p6.

It can't.

the properties of an element determine it's group placement, without knowledge of these properties (or, indeed, the element itself) it would be impossible to place an element in it's proper place on the periodic table.

Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.

mendeleev and others proposed the zero group

It is an incredibly small atom which gives it several uniqque properites.

1. It can ionise to leave a single proton with a very small radius (acid base reactions)

This element is likely to be Thallium based on its position in group 3A and period 6 of the periodic table. Thallium is a soft, malleable metal that is often used in electronic components and for its toxicity in certain compounds.

The element with 51 neutrons is antimony (Sb), which is a metalloid. Being in period 5, it belongs to the transition elements in the periodic table, showing typical metallic properties and variable oxidation states in its compounds.

There are many relatively new elements that have been added to the periodic table over the last few decades, like the element Copernicium, a man made element that was discovered by the Gesellschaft fur Schwerionenforschung (GSI) in 1996. And although there have not been any discoveries in the last 14 years, there are quantum physicists that spend there time looking for the next element.

There are no elements in titanium. Titanium is an element. It's a chemical element with the atomic number 22.

An atom can be found in a specific group on the periodic table based on its number of valence electrons. The group number indicates the number of valence electrons an atom has, which in turn determines its chemical properties and reactivity.

The group no. of Lithium is 1 and its period number is 2.

None of the Dobereiner triads are still listed in the same column of the modern periodic table. Dobereiner's triads were a set of three elements with similar chemical properties, but the modern periodic table is organized based on atomic number and electron configuration.

Fluorine is the element in group 17 (halogens) that is the least likely to lose an electron because it has the highest electronegativity in the group. Its strong attraction for electrons makes it more stable when gaining electrons rather than losing them.
