it's core charge would be +3
Explanation:
it's core charge would be +3
Explanation:
Answer: c. More than one population of a given species.
Explanation:
A habitat is a place or location which provide shelter and other necessary resources desired for survival.
Among the options given more than one population of a given species is correct option. This is because of the fact that if more than one population of species exists there will be competition for resources among the members this will lead to the decline in number of individuals in the populations.
A. lon charges are written as superscripts with the names of the
atoms.
B. Roman numerals are used instead of prefixes to indicate number.
C. Subscripts are used in the name to indicate number of atoms.
D. Ions combine in only one ratio.
Prefixes are not used to indicate the number of atoms when writing the chemical formula. The number of atoms are written as subscripts to their chemical symbols.
Chemical formula of a compound is used to identify a compound and distinguishes it from other compounds. A chemical formula is written from the chemical symbols of elements which constitute the compound.
The number of atoms of each element is written as the subscripts of the symbols for each atoms. For example,magnesium chloride contains one magnesium and two chlorine atoms thus, its formula is MgCl₂.
The subscripts for each atom in the formula of an ionic compound is the charge of the other atom into which it is bonded. Similarly, the formula of iron oxide containing 2 Fe and 3 O is written as Fe₂O₃.

Answer:
Ions combine into only one ratio
Explanation:
Just took test
b. electrons
c. poles
d. neutrons
Moving electrons create a magnetic field. The answer is letter B. This is because a charged particle moving without acceleration produces an electric field or magnetic field. It produces an electric field or magnetic field because it is charged.
(2) second electron shell
(3) third electron shell
(4) fourth electron shell
According to the electronic configuration, a calcium atom in the ground state electrons which possess least amount of energy are located in first shell.
Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elementshave valence shell complete in ground state and hence are said to be stable.
According to the electronic configuration,as the number of shells increases their energy also increases .Hence, electrons in first shell have least energy.
