Classifiion of Elements Classify each element as a metal, non-metal or metalloid based on it’s position on the Periodic Table.Also classify the family it is in. M = Metal NM = Non-Metal MO = Metalloid A. Halogen B. Transition Metal C. Alkaline
This element has more valence electrons than oxygen, fewer valence electrons than neon, more protons than sodium, but fewer protons than argon.
1 Answer to write the syol and name of each element: 1- the metalloid in family 15 closest in mass to the nobal gas Krypton 2- a representative element in the forth row that is an alkaline earth 3- a transition metal in the sixth row you expect to have chemical properties similar to zinc (z=30) 4- a nonmetal
c) Classify this element as a metal, nonmetal, or metalloid. d) In the box below, draw a Lewis electron-dot structure for this element. e) List two other elements likely to have properties similar to this element. Bonus (1 pt.) 1) The radius of a calcium ion is
Features of the Periodic Table Elements that have similar chemical properties are grouped in columns called groups (or families). As well as being nuered, some of these groups have names—for example, alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements).
Calcium is a shiny, silvery-white metal, When it is exposed to moist air, it readily tarnishes. At room temperature, calcium exists in the solid state and its melting point is 842 °C.

Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust

2020/3/26· Is Bromine a Metal or a Nonmetal? By Staff Writer Last Updated Mar 26, 2020 9:10:26 AM ET Iain George/CC-BY 2.0 Bromine is a nonmetal element. It takes a liquid form at normal room temperature and has a brownish-red color in both its gaseous and liquid
E ach element is assigned a unique one-, two-, or three-letter syol. The names of the elements are listed in the periodic table, along with their syols, atomic nuers, and atomic masses. The chemistry of each element is determined by its nuer of protons and electrons.

Chemical formulas – a group of chemical syols and nuers that represent the nuer of atoms of each element that make up a compound . ( H 2 O) In a chemical formula, the element with the positive charge is always written first. Chemical Formulas
A period 4 element is one of the chemical elements in the fourth row (or period) of the periodic table of the elements. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic nuer increases: a new row is begun when chemical behaviour begins to repeat, meaning
A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into …
Give the name and syol for the element that has mass nuer 64 and 35 neutrons. Copper, Cu 88. Classify each of the following as a metal, nonmetal, or metalloid. a. arsenic metalloid b. argon nonmetal c. calcium metal d. plutonium metal 89. Which of 16
The characteristic properties of metals and nonmetals are quite distinct, as shown in the table below. Metalloids, straddling the metal-nonmetal border, are mostly distinct from either, but in a few properties resele one or the other, as shown in the shading of the metalloid column below and summarized in the small table at the top of this section.
