Answer:
- <u>The elements that belong to the nitrogen family are nitrogen, phosphorus, arsenic, antimonium, bismuth, and moscovium.</u>
Explanation:
<em>Families</em> are group of elements that belong to the same column in the periodic table.
Some families have a well known name. For instance, alkali metals is the family of the elements that belong to the first column: Li, Na, K, Rb, Cs, and Fr (H is an exception, in spite it is in the first column it does not belong to the alkali metals family because it is a nonmetal). Other well known families are alkaline earth metals (column 2), halogens (column 3), and noble gases (column 18).
All the members of a family have the same number of valence electrons, i.e. electrons in the outermost shell.
- <u>Nitrogen</u>, N, is in the column 15; it has 5 valence electrons, because its outer most shell has configurarion ns²np³ (n is 2 because nitrogen is in the second period).
The other members fo this family with the electron configuration of the outermost shell are:
- <u>Phosphorus</u>, P, 3s² 3p³ (third period)
- <u>Arsenic,</u> As, 4s² 4p³ (fourth period)
- <u>Antimonium</u>, Sb, 5s² 5p³ (fith period)
- <u>Bismuth</u>, Bi, 6s² 6p³ (sixth period)
- <u>Moscovium</u>, Mc, 7s² 7p³ (seventh period)
Answer:
Copper
Explanation:
Metals are often arranged in crystalline lattices. The lattice consists of metal ions with an overlying sea of electrons. The conductivity of a metal depends on the nature of this crystal lattice. Naturally, some metals conduct electricity better than others. The unique properties of the crystal lattice of copper allow electrons to flow through it freely especially when it is drawn into a wire.
Answer:
<h2>One carbon atom forms four covalent bonds with four hydrogen atoms by sharing a pair of electrons between itself and each hydrogen (H) atom.</h2><h2>...</h2><h2>Properties of polar covalent bond:</h2><h2>Number of electron pairs shared Type of covalent bond formed</h2><h2>1 Single</h2><h2>2 Double</h2><h2>3 Triple</h2>
I'm just doing the ones that you don't have numbers already for.
2.) just leave it alone and it's correct
3.) Mg + 2AgNo3 --> Mg(No3)2 + 2Ag
5.) just leave it alone and it's correct
8.) 10C3H8O3 + 15O2 --> 30CO2 + 4H2O
10.) P4 + 6Br2 --> 4PBr3
12.) 2FeCl3 + 6NaOH --> 2Fe(OH)3 + 6NaCl
13.) 2CH3OH + 3O2 --> 2CO2 + 4H2O
14.) 2Al + 3Cu(NO3)2 --> 2Al(NO3)3 + 3Cu
15.) 3CaCl2 + 2K3AsO4 --> Ca3(AsO4)2 + 6KCl
16.) 2NH3 --> N2 + 3H2
17.) 2H3PO4 + 3Ba(OH)2 --> Ba3(PO4)2 + 6H2O
19.) Mg3N2 + 6H2O --> 3Mg(OH)2 + 2NH3
I hope this helps you!!
The element that is most reactive to gas is Hydrogen
